Photosynthesis is the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce glucose and oxygen. The chemical equation that represents photosynthesis is: sunlight + CO2 + H2O → C6H12O6 + O2. It takes place inside the chloroplasts of photosynthetic organisms, where chlorophyll absorbs sunlight and the thylakoids split water to produce oxygen and the stroma converts carbon dioxide into sugar. Photosynthesis converts solar energy into chemical energy stored in glucose and transforms carbon dioxide and water into energy-storing sugars and oxygen.

Biology Unit 3 Notes: Photosynthesis
Photosynthesis is the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce glucose and oxygen. It occurs in the chloroplasts of photosynthetic organisms, where chlorophyll absorbs sunlight that is used to convert carbon dioxide and water into oxygen and energy-storing glucose. Photosynthesis cycles matter and energy, converting sunlight into chemical energy stored in sugars and transforming carbon dioxide and water into oxygen and energy-rich organic compounds to fuel all other living things.
Biology Unit 3 Notes: Cellular Respiration
Cellular respiration is the process by which glucose and oxygen are broken down to produce carbon dioxide, water, and ATP through a series of chemical reactions. This occurs inside the mitochondria of cells in plants, animals, and bacteria. Glucose and oxygen are broken down to transfer energy to ATP molecules, while also cycling matter by taking glucose and oxygen and breaking their bonds to store energy and produce carbon dioxide and water. Cellular respiration and photosynthesis are connected processes, as respiration uses the glucose and oxygen produced by photosynthesis and produces the carbon dioxide and water needed for photosynthesis.

oxidation reduction reaction in living organisms
This document contains a lecture on oxidation-reduction (redox) reactions in living organisms:
1. Redox reactions involve the transfer of electrons and play a central role in metabolism. Photosynthesis and cellular respiration are important redox processes.
2. Photosynthesis uses redox reactions to convert sunlight into chemical energy by reducing carbon dioxide into glucose. Cellular respiration oxidizes glucose through a series of redox reactions to release energy in ATP.
3. Electron carriers like NAD+ and FAD shuttle electrons between reactions. As electrons move from higher to lower energy states, energy is released to power ATP synthesis through oxidative phosphorylation.
Photosynthesis and respiration
Photosynthesis uses carbon dioxide, water, and sunlight to produce glucose and oxygen through the process in chloroplasts. Cellular respiration uses glucose and oxygen to produce carbon dioxide, water, and ATP energy through the process in mitochondria. Both processes are contrasted, with photosynthesis producing glucose through chloroplasts in plants, and cellular respiration using that glucose and oxygen to produce energy in the mitochondria of plants and animals.
Photosynthesis and Respiration
The document summarizes the processes of photosynthesis and respiration. It describes:
1) Photosynthesis uses carbon dioxide, water, and sunlight to produce oxygen and glucose through two stages: capturing the sun's energy and using that energy to produce sugars.
2) Respiration breaks down glucose and other foods to release the stored energy through a two stage process in the cytoplasm and mitochondria.
3) Photosynthesis and respiration are interconnected processes, with one producing the inputs for the other.
Photosynthesis and Cellular Respiration
Photosynthesis and respiration are reactions that complement each other in the environment. They are in reality the same reactions but occurring in reverse. While in photosynthesis carbon dioxide and water yield glucose andoxygen, through the respiration process glucose and oxygen yield carbon dioxide and water.
They work well since living organisms supply plants with carbon dioxide which undergoes photosynthesis and produces glucose and these plants and bacteriagive out oxygen which all living organisms need for respiration.
Photosynthesis is a process that converts carbon dioxide into organic compounds in presence of sunlight. Respiration is the set of metabolic reactions that take in cells of living organisms that convert nutrients like sugar into ATP (adenosine tri phosphate) and waste products.
Processes in photosynthesis are divided on basis of requirement of sunlight while respiration processes are divided on basis of requirement of oxygen. Hence in photosynthesis you have the light dependent reactions and the dark reactions while inrespiration there is aerobic respiration and anaerobic respiration.
In photosynthesis light dependent reactions, ultra violet light strikes chlorophyll pigments which excites electrons leading to separation of oxygen molecules from carbon dioxide. In the dark reactions, carbon molecules now independent of oxygen are converted into carbohydrates and stored in plant cells as energy and food source. In aerobic cellular respiration oxygen is utilized to convert organic compounds into energy and in anaerobic respiration converts organic compounds into energy without using oxygen.

Lesson Plan Revised
Photosynthesis converts light energy from the sun into chemical energy stored in glucose. It occurs in two stages - the light dependent reactions in the thylakoid membrane that use light energy to produce ATP and NADPH, and the light independent reactions in the stroma that use ATP, NADPH, and CO2 to produce glucose. Most of the oxygen produced as a byproduct of photosynthesis comes from phytoplankton in the ocean, not land plants.

- Photosynthesis converts sunlight, carbon dioxide and water into oxygen and glucose (chemical energy stored in food).
- It takes place in chloroplasts within plant cells, using chlorophyll and a membrane system to transform light energy into ATP and NADPH through light-dependent reactions, and using those products to fix carbon and produce glucose through light-independent reactions.
- Photosynthesis is essential to life on Earth as it provides oxygen for animals to breathe and produces food/glucose that sustains life.
Oxygen presentation
Oxygen is an element with the symbol O and 8 electrons. It is essential for breathing and comes from trees. Oxygen is needed by people and animals, it is a gas, and is required for burning materials. The periodic table shows elements and their protons/electrons. The oxygen cycle connects oxygen in nature and living things.

Presentation1
Photosynthesis is the process by which plants produce their own food. It involves combining carbon dioxide, water, and sunlight to produce glucose and oxygen. There are four stages of photosynthesis: 1) Light absorption, where chlorophyll absorbs sunlight to power the process, 2) Electron transport, where electrons are transferred through membranes, 3) ATP generation, where ATP is synthesized, and 4) Carbon fixation, where carbon dioxide is converted into sugars using ATP and NADPH.

Photosynthesis
Photosynthesis is the process by which plants produce glucose from carbon dioxide and water, releasing oxygen as a byproduct. It occurs in two phases - the light reaction, where sunlight is absorbed to produce ATP and NADPH using water, and the dark reaction, where carbon dioxide reacts with ATP and NADPH to form glucose. Key steps include the splitting of water molecules during the light reaction, carbon dioxide entering the plant and reacting with RuBP during the dark reaction, and the production of glucose as the final product. The rate of photosynthesis is affected by factors like the availability of carbon dioxide, water, chlorophyll, and sunlight.
15 photosynthesis
Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce oxygen and energy in the form of ATP and NADPH. It occurs in chloroplasts, which contain chlorophyll and other pigments. Photosynthesis involves two photosystems which absorb light and use it to split water, producing oxygen, protons, and electrons. The electrons are used to produce ATP through electron transport, and NADPH through oxidative phosphorylation. The ATP and NADPH produced are then used by the Calvin cycle to fix carbon dioxide into sugars.
Respiration in plants (Do plants breathe and Glycolysis)
Plants do breathe and require oxygen for respiration, producing carbon dioxide as a byproduct. Unlike animals, plants do not have specialized organs for gas exchange, but instead use stomata and lenticels. Each plant part is responsible for its own gas exchange at lower respiration rates than animals. Aerobic respiration utilizes oxygen to produce carbon dioxide, water, and energy from glucose. Glycolysis is the first step and breaks glucose down into two molecules that enter the payoff phase, producing two ATP molecules, two NADH molecules, and two pyruvate molecules as end products.
Respiration and Photosynthesis
Photosynthesis and respiration are closely related processes. Photosynthesis produces energy through chloroplasts in plants, while respiration uses this energy in mitochondria of cells. There are two types of respiration - aerobic respiration requires oxygen and occurs in mitochondria, while anaerobic respiration does not require oxygen and includes lactic acid fermentation in muscles and alcohol fermentation in rising bread.
Cellular respiration introduction for 9th grade biology
Cellular respiration is the process cells use to release energy stored in glucose and store it in ATP. It occurs in three main stages:
1. Glycolysis breaks glucose into pyruvate, producing 2 ATP.
2. The citric acid cycle in the mitochondria further breaks down pyruvate, producing more ATP, CO2, and electron carriers.
3. The electron transport chain uses oxygen to generate most of the cell's ATP through oxidative phosphorylation as electrons are passed through protein complexes, producing up to 36 ATP per glucose molecule.
Respiration and it's types in plants
it's about the respiration in plants and also types of respiration include with stages of respiration.
Cells and Energy
Cellular respiration is a series of chemical reactions that convert energy from food into a usable form called ATP. It takes place in two steps - glycolysis in the cytoplasm breaks down glucose, producing some ATP and precursor molecules, while the second step in mitochondria uses oxygen to break down these precursors and produce much more ATP. Fermentation is an alternative pathway used without oxygen to produce less ATP. Photosynthesis converts light energy, carbon dioxide, and water into glucose and oxygen through reactions in chloroplasts.
Respiration in Plants (Types)
1) Respiration in plants involves the breakdown of carbohydrates, proteins and fats to release energy and produce carbon dioxide and water. It helps plants produce food and energy for growth, development and other functions.
2) There are two types of respiration - aerobic respiration which occurs in the presence of oxygen and yields more energy, and anaerobic respiration which occurs without oxygen and yields less energy.
3) Fermentation is a type of anaerobic respiration that produces ethanol, lactic acid or other products, and involves glycolysis but not the Krebs cycle or electron transport chain. It is used commercially in producing foods and chemicals.

It occurs in two stages - the light-dependent reaction which converts solar energy to chemical energy in the form of ATP and NADPH, and the light-independent reaction which uses this chemical energy to fix carbon and produce glucose. Photosynthesis is essential as it produces oxygen and glucose, the primary energy source for nearly all life on Earth.

It occurs in chloroplasts in plant cells and involves the absorption of light, transfer of electrons, and synthesis of ATP and NADPH followed by carbon fixation through the Calvin cycle.
Unit 3 Biology Study Cards
Proteins are made up of amino acid monomers linked together by peptide bonds. They are synthesized through transcription and translation processes involving DNA, RNA and ribosomes. Proteins have four levels of structure - primary, secondary, tertiary and quaternary - which determine their shape and function. Proteins perform many essential roles in cells and organisms such as catalysis, structure, defense and transport.
Ch 10: Photosynthesis
Photosynthesis is the process by which plants, algae, and some bacteria use sunlight, water and carbon dioxide to produce oxygen and energy in the form of glucose. It occurs in chloroplasts and involves two stages - the light-dependent reactions where ATP and NADPH are produced, and the light-independent Calvin cycle where glucose is formed. Chlorophyll and other pigments absorb sunlight which is used to power the transfer of electrons and production of chemical energy carriers. Photosynthesis ultimately feeds the biosphere by producing organic molecules and oxygen from inorganic sources.
Cells And Enzymes
The document discusses key concepts about enzymes and catalysts including:
1. Catalysts speed up chemical reactions without being changed themselves. Enzymes are biological catalysts that help break down or build up molecules in living things.
2. Each enzyme has a unique 3D shape that allows it to bind specifically to one substrate. The active site is where this binding occurs.
3. Enzymes can catalyze both breakdown reactions, which break large molecules into smaller ones, and synthesis reactions, which build small molecules into larger ones.
4. The optimum temperature and pH are the conditions under which an enzyme works best. Changing conditions can cause the enzyme to denature and lose its shape/
Ch 17: From Gene to Protein
This document summarizes key concepts from a lecture on gene expression from DNA to protein. It discusses:

2) Experiments by Beadle and Tatum showing that mutations in neurospora resulted in inability to synthesize specific enzymes, supporting the "one gene-one enzyme" hypothesis.
3) The genetic code is cracked - codons of 3 nucleotide bases in mRNA specify 20 different amino acids or stop signals in proteins. The code is nearly universal across life.
Introduction To Biology Notes
This document provides an overview of key concepts in biology covered in a textbook. It discusses the 7 characteristics of life, including organization, cells, response to stimuli, homeostasis, metabolism, growth and development, reproduction, and evolution. It also covers major themes in biology like diversity and unity of life, interdependence of organisms, and evolution. The scientific process is outlined, from making observations and forming hypotheses to designing experiments, analyzing data, and constructing theories. Finally, it discusses tools used in biology like microscopes and the metric system of measurement.
Protein Synthesis
Proteins are macromolecules built up of amino acid monomers that play key roles in living organisms. DNA contains instructions for producing proteins, but proteins are manufactured by ribosomes in the cell cytoplasm, so a two-stage process called protein synthesis is needed to transfer the DNA instructions. In the first stage, transcription, a messenger RNA molecule is produced from DNA in the nucleus. In the second stage, translation, the mRNA leaves the nucleus and attaches to ribosomes, where amino acids are linked together into a polypeptide chain according to the mRNA's triplet code.
17 - From Gene to Protein
This document provides an overview of the process by which DNA directs protein synthesis through transcription and translation. It discusses the flow of genetic information from DNA to mRNA to protein. Key points include: transcription produces messenger RNA from DNA templates in the nucleus; eukaryotic pre-mRNA is processed before translation; translation occurs in the cytoplasm using tRNA to add amino acids to growing polypeptide chains on ribosomes according to mRNA codons. The genetic code is nearly universal and specifies 20 amino acids using triplets of nucleotides.
18 Regulation of Gene Expression
This document summarizes regulation of gene expression in bacteria and eukaryotes. It discusses how bacteria regulate genes through the operon model, including repressible and inducible operons like the trp and lac operons.

Cellular respiration is the process by which glucose and oxygen are broken down to produce carbon dioxide, water, and ATP through a series of chemical reactions. This occurs inside the mitochondria of plant, animal, bacteria, and other living cells. The process transfers energy from glucose to ATP and transforms glucose and oxygen into carbon dioxide, water, and energy-storing ATP molecules that power cellular functions. Cellular respiration and photosynthesis are connected processes, as respiration uses the glucose and oxygen produced by photosynthesis and produces the carbon dioxide and water needed for photosynthesis.

The document discusses photosynthesis and the carbon cycle. It explains that:
1) Photosynthesis uses energy from sunlight to convert carbon dioxide and water into oxygen and carbohydrates like sugar, storing the sun's energy.
2) Carbon cycles between the atmosphere, living things, oceans, soil and fossil fuels as part of the global carbon cycle. Green plants and algae absorb carbon dioxide and release oxygen through photosynthesis.
3) Photosynthesis occurs in chloroplasts and has two stages - the light dependent reactions which require sunlight, and the light independent dark reactions which can occur with or without light but are more efficient in darkness.
Ths general biology unit 1 our environment photosynthesis notes_v1516
Plants, algae, and some bacteria perform photosynthesis, which uses sunlight, carbon dioxide, and water to produce oxygen and glucose (sugar). Photosynthesis occurs in chloroplasts and converts the sun's energy into chemical energy stored in sugar, which all living things rely on. It rearranges carbon, oxygen, and hydrogen atoms from carbon dioxide and water into oxygen gas and glucose.

The document summarizes the process of photosynthesis, which is a chemical reaction that converts light energy from the sun into chemical energy stored as glucose. It occurs in the chloroplasts of plant leaves using chlorophyll and produces oxygen as a byproduct. The process involves carbon dioxide and water reacting to form glucose and oxygen.
PHOTOSYNTHESIS in plants and others.ppt
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
photosynthesis
This document provides an overview of photosynthesis. It explains that photosynthesis requires carbon dioxide, water, and sunlight as inputs. The light-dependent reactions use sunlight to produce ATP and NADPH, while the light-independent reactions use ATP and NADPH to produce glucose from carbon dioxide. Photosynthesis is important as it provides food for other organisms, removes carbon dioxide from the atmosphere, and supports industrial activities that rely on plant materials.
oxidation and reduction reaction in living system.pptx
Oxidation-redox reactions involve the transfer of electrons, with oxidation occurring when electrons are lost and reduction when electrons are gained. These reactions are important in living systems, powering processes like photosynthesis and respiration. Photosynthesis uses energy from sunlight to oxidize water and reduce carbon dioxide into organic molecules like glucose. Cellular respiration then oxidizes glucose and reduces oxygen, generating energy through redox reactions and recycling carbon dioxide and water. Redox reactions are thus vital to basic life processes and play a role in metabolic pathways through electron carrier molecules.
Cell energy 1: Photosynthesis
Photosynthesis is the process by which plants, algae, and some bacteria use sunlight, water and carbon dioxide to produce oxygen and energy in the form of glucose. It occurs in two stages: the light-dependent reactions where light energy is captured to make ATP and NADPH, and the light-independent reactions where carbon dioxide is incorporated into organic compounds to make glucose. The rate of photosynthesis depends on factors like light intensity, carbon dioxide concentration, temperature, and amount of chlorophyll present. Photosynthesis is essential as it provides the primary source of energy and organic molecules on Earth.
Photosynthesis
The document discusses photosynthesis and how it is the process by which plants, algae, and some bacteria use sunlight, water and carbon dioxide to produce oxygen and energy in the form of glucose. It explains that chloroplasts are the sites of photosynthesis and contain chlorophyll, which absorbs sunlight that is converted to chemical energy. The light reactions use sunlight to make ATP and NADPH, while the dark reactions, such as the Calvin Cycle, use this energy to fix carbon from carbon dioxide into organic molecules like glucose. Photosynthesis is essential as it produces oxygen and feeds the base of the food chain.
Photosynthesis and Cellular Respiration-0.ppt
1. The document outlines photosynthesis and cellular respiration, including their processes, structures, and importance.
2. Photosynthesis uses light energy, water and carbon dioxide to produce oxygen and sugars like glucose in chloroplasts. Respiration uses oxygen and sugars to produce carbon dioxide, water and energy in mitochondria.
3. These processes are complementary as photosynthesis provides the oxygen and sugars used for respiration, which in turn produces the carbon dioxide and water used by photosynthesis.
photosynthesis.pptx
Photosynthesis occurs in chloroplasts and involves two main stages. In the light-dependent reactions, chlorophyll absorbs light energy which splits water molecules into oxygen, protons, and electrons. The Calvin cycle then uses these products to convert carbon dioxide into glucose through chemical reactions, producing oxygen as a byproduct. Photosynthesis is essential as it is how energy from the sun is captured and stored as chemical energy in sugars, the primary food source for most living things.
Photosynthesis
Plants and algae perform photosynthesis, which converts carbon dioxide and water into glucose and oxygen using energy from sunlight. Photosynthesis occurs in chloroplasts and uses chlorophyll to absorb light, which drives the production of ATP and NADPH that fuel the Calvin cycle to produce glucose from carbon dioxide. It is an essential process that generates oxygen and forms the base of the food chain sustaining all life on Earth.

Anatomy-Bad Fish Unit: Digestion Notes
This document describes digestion that occurs in the mouth, esophagus, stomach, and small intestine. In the mouth, food is mechanically and chemically broken down by teeth and saliva enzymes. The chewed food or bolus is then swallowed through the esophagus using peristalsis. In the stomach, the bolus is further broken down by stomach muscles and enzymes in gastric juice. When fully digested, the liquid chyme exits the stomach into the small intestine where bile, pancreatic juice, and bicarbonate aid in further digestion before nutrients are absorbed in the jejunum and ileum.
Anatomy-Bad Fish Unit: Cardiovascular Notes
The heart has four chambers separated by a septum, with two atria that receive blood and two ventricles that pump blood out. It is surrounded by membranes and layers. Veins carry deoxygenated blood into the right atrium while pulmonary veins carry oxygenated blood into the left atrium. The pulmonary artery carries blood from the right ventricle to the lungs and the aorta carries it from the left ventricle throughout the body. Valves ensure blood flows in one direction. The cardiac cycle involves the heart relaxing to fill with blood then contracting to pump it out in two phases controlled by the conduction system.

This document outlines a workshop on creating curriculum units from scratch using case studies and new standards. The workshop agenda includes an introduction, explaining why use case studies, and walking through the steps of transforming a case study into a curriculum. The steps include: reading the case study and identifying vocabulary and questions; connecting disciplinary core ideas (DCIs) to the questions; determining the driving question and final goals; finding activities that incorporate science practices; and finalizing the curriculum with assessment and starting the case study. The goal is to share the presenter's experience developing original units and help teachers who teach without prepared curricula.
Ths general biology unit 4 heredity non mendelian genetics notes_v1516
This document discusses different types of non-Mendelian genetics including polygenic traits which are influenced by multiple genes, codominant traits where both alleles are expressed together, incomplete dominance where the heterozygote exhibits a blending of traits, and sex-linked traits located on the sex chromosomes. Examples are provided for each type to demonstrate inheritance patterns that differ from simple Mendelian genetics.
Ths general biology unit 4 heredity mendelian genetics notes_v1516
This document summarizes key concepts in Mendelian genetics. It explains that Gregor Mendel studied trait inheritance in pea plants and discovered that traits can be dominant or recessive. Dominant traits always appear if present, while recessive traits only appear if an organism inherits two recessive alleles. An organism's genotype describes its genetic makeup, while its phenotype describes its physical traits. Punnett squares are used to predict the probability that offspring will inherit different combinations of alleles from their parents.
Ths general biology unit 4 heredity karyotyping notes_v1516
Karyotyping is used to identify chromosomal disorders by staining and organizing chromosomes from longest to shortest based on banding pattern. Abnormalities include an extra chromosome like Trisomy 21 which causes Down Syndrome characteristics such as cognitive impairment and heart defects, or a missing sex chromosome as in Turner's Syndrome where females are sterile with short stature.
Ths general biology unit 4 heredity reproduction and meiosis notes_v1516
Meiosis is the process of cell division that produces gametes (sperm and egg cells) for sexual reproduction. It involves two cell divisions that result in four haploid cells, each with half the number of chromosomes as the original cell. This ensures that offspring have a full set of chromosomes when fertilization occurs. The main features of meiosis include homologous chromosome pairing, crossing over to increase genetic variation, and independent assortment of chromosomes into daughter cells through the first and second meiotic divisions. Errors in meiosis can result in gametes with an abnormal number of chromosomes, causing genetic disorders.
Ths general biology unit 4 heredity protein synthesis notes_v1516
Protein synthesis involves two main steps: transcription and translation. In transcription, the DNA code is copied into messenger RNA (mRNA) in the cell nucleus. This mRNA then leaves the nucleus and the code is translated during translation when transfer RNA (tRNA) matches mRNA codons and brings corresponding amino acids to form a protein, guided by ribosomal RNA (rRNA). Mutations occur when the DNA code changes, leading to errors in protein synthesis when the wrong tRNA and amino acids are matched to the altered mRNA codons.
Ths general biology unit 4 heredity cell cycle notes
Cell division allows cells to grow, repair, replace damaged cells, and reproduce. There are two main types of cell division: mitosis and meiosis. The cell cycle is the process cells use to prepare for cell division. It includes interphase, where the cell grows and duplicates its DNA, and the M phase where the cell divides. Errors in the cell cycle checkpoints during interphase can allow defective cells to divide uncontrollably and cause cancer.
Ths general biology unit 4 heredity dna replication notes
DNA replication is necessary for cell division to create a copy of the DNA for each new cell. Messelson and Stahl discovered that DNA replication is a semi-conservative process where the original DNA molecule splits into two new molecules, each with one original strand and one newly synthesized complimentary strand. The basic steps of replication are to unwind the DNA strands, separate the strands, and then make complimentary copies of each single strand to result in two new DNA molecules with one old and one new strand each.
Ths general biology unit 4 heredity dna structure and function notes
DNA stores genetic instructions in the form of a code made up of four nitrogenous bases: adenine (A), thymine (T), guanine (G), and cytosine (C). DNA has a double-stranded helical structure, with the strands bonded together via complementary base pairing between A and T and between G and C. According to Chargaff's rule, the percentage of A bases is always equal to the percentage of T bases, and the percentage of G bases is always equal to the percentage of C bases within a DNA sample. The two strands of DNA run in opposite directions of each other (anti-parallel) and form a double helix.

Homeostasis refers to maintaining internal balance, and feedback mechanisms are the involuntary chemical processes that bring the body back to its normal state when something causes internal changes. There are two main types of feedback mechanisms: negative feedback mechanisms return the body to its normal state, like shivering and sweating to regulate temperature and insulin to regulate blood sugar levels. Positive feedback mechanisms cause more change to happen, though few homeostatic responses use this type, such as oxytocin causing stronger contractions during childbirth to help deliver the baby.
Ths general biology unit 2 our bodies living organization notes_v1516
All living things are made of cells and molecules that are organized into different levels. Cells are the basic units of life that make up tissues, organs, organ systems, and the overall organism. All cellular processes require energy and involve the movement and reactions of molecules like carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. Homeostasis is maintained involuntarily within cells and organisms through processes that keep internal stability and balance. Cells become specialized by taking on unique shapes and functions to complete specific roles that together support homeostasis at the organism level. The main human organs include the brain, heart, lungs, liver, stomach, intestines, and kidneys, each of which performs crucial functions for keeping humans alive and healthy.
Ths general biology unit 2 our bodies cells and organelles notes_v1516
(1) Cells are the basic unit of life and can be either unicellular (single-celled) or multicellular (many cells). Cells contain organelles that help them complete important processes.
(2) Key organelles include the nucleus, ribosomes, endoplasmic reticulum, Golgi body, mitochondria, chloroplasts, cell membrane, and cell wall.
(3) Organelles are found inside cells to help them carry out specialized functions like protein production, cellular respiration, and photosynthesis. The endosymbiotic theory explains how organelles may have originally been independent organisms that lived inside host cells and eventually became permanent cell structures.
Ths general biology unit 2 our bodies cell reactions and enzymes notes_v1516
Cellular reactions use enzymes to break down molecules, form larger molecules, and facilitate energy storage and release using ATP and ADP. Enzymes are proteins that catalyze chemical reactions by lowering their activation energy through a specific lock-and-key structure that allows substrates to bind at the enzyme's active site. Denaturing enzymes through extreme heat or chemicals causes their structure to unravel and disrupt their active site, preventing them from catalyzing reactions.

This document discusses key concepts around biodiversity, ecosystem stability, and succession. It defines biodiversity as the variety of living organisms in an ecosystem, and notes that greater biodiversity leads to greater ecosystem stability. Succession is introduced as the process by which the structure of a community changes over time due to events like fires, storms, or human activity. There are two types of succession: primary succession, which occurs in a new area without soil or life, and secondary succession, which follows a disruption to an already established habitat.
