Photosynthesis and Cellular Respiration
The document discusses photosynthesis and cellular respiration. It provides information on:
- The chemical equation for photosynthesis, which converts carbon dioxide and water into glucose and oxygen using sunlight.
- Cellular respiration, which breaks down glucose in mitochondria to release energy in cells.
- Photosynthesis and cellular respiration are interrelated processes - photosynthesis produces glucose that is used for energy in cellular respiration, and cellular respiration releases carbon dioxide and water used in photosynthesis.
12 syllabus statements
Respiration involves the action of enzymes in cells and can occur aerobically or anaerobically. Aerobic respiration uses oxygen to break down glucose into carbon dioxide and water, releasing energy. Anaerobic respiration breaks down glucose without oxygen, releasing less energy and products like alcohol or lactic acid. Lactic acid builds up in muscles during vigorous exercise without oxygen and is later removed by aerobic respiration in the liver during recovery.
Photo respiration (1)
Cells require energy to perform essential functions like movement, shape change, repair, and transport. Autotrophs can produce their own food through photosynthesis, which converts sunlight into the chemical energy of sugars. Photosynthesis occurs in plant leaves through chloroplasts and involves three stages: light energy is captured and used to make ATP and NADPH, which are then used to produce carbohydrates from carbon dioxide and water. The process is influenced by factors like light, concentration of materials, and temperature.
Photosynthesis
The document provides an overview of photosynthesis, including:
1) The importance of autotrophs in providing energy and carbon compounds for all organisms and oxygenating the atmosphere.
2) An overview of the light-dependent and light-independent reactions of photosynthesis, which use energy from sunlight to produce oxygen and carbohydrates from carbon dioxide and water.
3) The structures of leaves and chloroplasts that are important sites for photosynthesis.
photosynthesis ppt
Photosynthesis is the process by which plants, algae, and cyanobacteria use sunlight, water and carbon dioxide to produce oxygen and energy in the form of food (sugars). It occurs in two stages: (1) the light reactions where sunlight is absorbed and converted to chemical energy in the form of ATP and NADPH, and (2) the dark reactions where carbon dioxide is fixed using the ATP and NADPH to produce sugars like glucose. The overall equation is: 6CO2 + 6H2O + sunlight → C6H12O6 (glucose) + 6O2. Photosynthesis provides a critical source of food for organisms and oxygen for respiration.

Photosynthesis introduction for Advanced Biology 9th grade
Photosynthesis is the process by which plants convert light energy from the sun, carbon dioxide from the air, and water from the soil into glucose and oxygen. It occurs in two stages: in the light reactions, light energy, water, and carbon dioxide are used to produce ATP, NADPH, and oxygen; and in the Calvin cycle, ATP, NADPH, and carbon dioxide are used to produce glucose.
Photosynthesis in land plants
This document discusses photosynthesis and defines it as the process by which plants convert light energy from the sun, carbon dioxide, and water into chemical energy stored as glucose. It states that photosynthesis takes place in chloroplasts, which contain the green pigment chlorophyll. The key components needed for photosynthesis are light, carbon dioxide, and water. The equation for photosynthesis is provided as carbon dioxide + water + light energy → glucose + oxygen. Structures involved in photosynthesis like the chloroplast, thylakoid membrane, and photosystems are also outlined.
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 sugar. It occurs in two stages: in stage one, chloroplasts in plant cells capture sunlight and use its energy to power stage two, where carbon dioxide and water are converted into oxygen and glucose using an enzyme-driven process. Cellular respiration is the process by which cells generate energy by breaking down glucose molecules in the presence of oxygen. It also occurs in two stages: in stage one, glucose is broken down into smaller molecules in the cytoplasm, and in stage two these molecules are further broken down in the mitochondria to release energy, carbon dioxide and water.
LT2.1 Photosynthesis PowerPoint Notes
The document discusses photosynthesis and provides information about the process. It defines photosynthesis as the process by which sunlight energy is converted to glucose energy. It also notes that photosynthesis occurs in the chloroplasts of plants and involves the reactants of carbon dioxide, water, and sunlight being converted to the products of glucose and oxygen. Producers that undergo photosynthesis supply the entire food chain with energy.
Photosynthesis
Photosynthesis is the process plants use to make their own food, using chlorophyll in their leaves to absorb sunlight. The sunlight is combined with water, carbon dioxide, and nutrients from the soil, which the chlorophyll then processes to make sugars and oxygen. Plants and animals depend on each other to survive, as animals produce the carbon dioxide plants need for photosynthesis and plants produce the oxygen and food that animals need.
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.
Oxygen cycle
All living things rely on oxygen, which is produced through photosynthesis by plants and algae. During photosynthesis, plants use carbon dioxide and water to produce oxygen and glucose. Animals and other organisms use oxygen to break down glucose through cellular respiration, releasing energy, water, and carbon dioxide. This exchange of oxygen and carbon dioxide between photosynthesizing organisms and respiring organisms makes up the oxygen cycle that is essential for life.
Photosynthesis Notes PPT
The document provides information about the process of photosynthesis. It explains that photosynthesis takes place in the chloroplasts of plant cells, where chlorophyll absorbs light energy and uses it to convert carbon dioxide and water into glucose and oxygen. The process involves two stages - the light-dependent reaction that uses light to produce ATP and NADPH, and the light-independent Calvin cycle that uses the ATP and NADPH to fix carbon dioxide and produce glucose. Plants appear green because chlorophyll, the pigment that absorbs light for photosynthesis, reflects green light wavelengths.
Biology unit 3 cell energy intro to energy notes
Energy is needed by living things to perform life processes like growth, reproduction, metabolism, and homeostasis. There are two main types of energy: chemical potential energy stored in molecular bonds, and kinetic energy used in reactions. Both energy and matter cycle continuously throughout the environment as molecules are broken down, releasing energy to other systems, and built back up, storing energy for later use. ATP stores energy in phosphate bonds and can release energy when its third phosphate is removed, while ADP can store energy when a third phosphate is added.

Photorespiration
This document is a student paper on the topic of photorespiration in plants. It defines photorespiration as a process in plant metabolism that attempts to reduce the wasteful oxygenation reaction of the enzyme RuBisCO. The paper then discusses what happens during photorespiration, noting that oxygen replaces carbon dioxide in a non-productive reaction, decreasing the net carbon dioxide converted to sugars. Finally, it mentions that photorespiration limits plant growth and is favored by high oxygen, low carbon dioxide, and warm temperatures.
How plants-get-food
Van Helmont, a 17th century Belgian physician, conducted an experiment where he planted a willow sapling in soil and measured its growth over 5 years with only water added. The tree gained 74kg in weight while the soil only lost 52g, leading van Helmont to conclude the tree obtained its food from water alone. However, he overlooked the role of carbon dioxide from the air, which plants combine with water through photosynthesis to make glucose and oxygen. This process requires energy from sunlight absorbed by the chlorophyll in plant leaves. Plants use glucose for energy but also combine it with ions like nitrogen taken from the soil to make proteins and other substances needed for growth.

It tests for the presence of starch after exposing plants to different conditions such as removing carbon dioxide, chlorophyll, or sunlight. The experiments involve destarching plants, exposing them to conditions, then testing for starch using iodine to determine if photosynthesis occurred. Graphs show that starch is only produced when conditions like carbon dioxide and light are present.
Photosynthesis and environment.pptx
Photosynthesis and respiration are important chemical reactions that occur in plants. Photosynthesis uses carbon dioxide, water, and sunlight to produce glucose and oxygen. The equation for photosynthesis is: 6CO2 + 6H2O + Energy → C6H12O6 + 6O2. Cellular respiration breaks down glucose and uses oxygen to produce carbon dioxide, water, and ATP (energy). The equation for respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy. In plants, photosynthesis occurs during the day while respiration occurs both day and night, with the two processes balancing the intake and output of gases.

Photosynthesis C3 and C4 cycle, Dr.Kamlesh shah, PSSHDA,KADI
Bacterial photosynthesis involves light-harvesting pigments that capture light energy and transfer it to reaction centers. The energy is converted to electrons that are fed into an electron transport chain, generating a proton motive force used by ATPases to make ATP. There are five photosynthetic bacterial groups classified based on 16S rRNA, including oxygenic cyanobacteria/prochlorophytes and anoxygenic purple bacteria, green sulfur bacteria, heliobacteria, and green gliding bacteria. Oxygenic photosynthesis results in O2 release and CO2 removal using two photosystems, while anoxygenic photosynthesis uses bacteriochlorophyll and one photosystem to generate ATP without O2 production.

3) Photosynthesis converts sunlight into chemical energy stored in sugars, providing energy and materials for plants and the global biosphere.
Cells And Photosynthesis
This document covers photosynthesis and includes objectives, definitions, diagrams, and experiments. It discusses how plants perform photosynthesis to produce carbohydrates from carbon dioxide and water using energy from sunlight. The process has two stages - photolysis where light energy splits water, producing oxygen and hydrogen used in the second stage. The second stage is carbon fixation where carbon dioxide is combined with hydrogen to form glucose. The document also describes how plants store carbohydrates as starch and use cellulose in cell walls.

Photosynthesis
The document discusses photosynthesis and the factors that affect its rate. It explains that the three limiting factors of photosynthesis are light intensity, carbon dioxide concentration, and temperature. Graphs show how the rate levels off or declines when these factors become limited. Horticulture can help reduce these limiting effects by providing extra lighting to greenhouses, increasing temperature which also releases more carbon dioxide, and allowing for increased and earlier crop yields under more controlled conditions.
Be 4100 carbon fix project
The goal of the study was to design a continuous stirred-tank reactor (CSTR) to capture 10 mg/L-day of atmospheric carbon using algal cultures. A model of the CSTR was developed using the Monod equations to describe microbial growth. The model found that a hydraulic retention time of 70 hours would allow the reactor to capture carbon at a rate of 10.55 mg/L-day. This meets the design goal of 10 mg/L-day. The optimal conditions include a biomass concentration of 12 mg/L, substrate concentration of 1 mg/L, and specific growth rate of 0.1023 hr-1.
Calvins-cycle.pdf for stem students future
The Calvin cycle is the set of reactions in photosynthesis that uses energy from sunlight to fix carbon dioxide and produce glucose and other carbohydrates. The cycle has three stages: 1) carbon fixation using the enzyme RuBisCO to incorporate CO2 into an organic molecule, 2) reduction of the organic molecule using ATP and NADPH, 3) regeneration of RuBP to restart the cycle. Through multiple turns of the Calvin cycle, six molecules of CO2 are fixed to produce one molecule of glucose.
10photosynthesis 130311053414-phpapp01
1. The document discusses photosynthesis, 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.
2. Photosynthesis occurs in two stages - the light reactions where solar energy is captured and used to produce ATP and NADPH, and the Calvin cycle where carbon is incorporated into organic molecules like glucose.
3. The light reactions take place in the thylakoid membranes of chloroplasts and use photon energy to establish a proton gradient across the membrane, driving ATP synthesis via chemiosmosis.
Light independent react
The document discusses the Calvin cycle and how it uses ATP and NADPH to convert CO2 into sugar. It explains that CO2 enters the cycle and is converted into a three-carbon sugar called glyceraldehyde-3-phosphate (G3P) through three phases: carbon fixation, reduction, and regeneration of the CO2 acceptor. The cycle regenerates its starting material and fixes carbon from three CO2 molecules to produce one G3P molecule.
Photosynthesis Lab Report
This lab report examines the effect of light conditions on the rate of photosynthesis. The experiment measured the rate of photosynthesis by timing how long it took for photosynthesis to occur in leaf disks placed in a CO2 solution under different lighting conditions. As predicted, the results showed that the rate of photosynthesis was higher for leaf disks in direct sunlight compared to those in the shade. The conclusion was that light and carbon dioxide are necessary for photosynthesis, and that more light leads to a higher photosynthetic rate.
Carbohydrates- classification, identification and biosynthesis
In this power point presentation viewers will be able to know about the basic idea about carbohydrates. How to classify the carbohydraters depends on the moeities present. The identification tests for carbohydrates also has been discussed.
Photosynthesis
Photosynthesis is the process by which plants use sunlight, carbon dioxide and water to produce oxygen and energy in the form of glucose. It occurs through two stages - the light-dependent reactions where ATP and NADPH are produced, and the light-independent Calvin cycle where glucose is produced. All living organisms ultimately depend on photosynthesis, which takes place primarily in the chloroplasts of plant leaves using the pigments chlorophyll a and b. The rate of photosynthesis is affected by factors like light intensity, carbon dioxide concentration, temperature and water availability.
First Paper
This document describes an approach to rapidly generate molecular diversity using photoassisted diversity-oriented synthesis. Linear photoprecursors containing amino ketone and unsaturated pendant groups are assembled using high-yielding coupling reactions. These precursors undergo efficient intramolecular photocyclizations upon irradiation to form polyheterocyclic scaffolds with increased saturation, reduced rotatable bonds, and new structural frameworks. The primary photoproducts contain reactive functional groups that allow for further post-photochemical modifications, growing molecular complexity and accessing elaborated three-dimensional structures. This modular approach aims to generate drug-like molecules with properties known to correlate with clinical success, overcoming limitations of traditional combinatorial chemistry methods.
Photosynthesis cellular respiration
Photosynthesis and cellular respiration are opposite but complementary processes. Photosynthesis uses carbon dioxide, water, and sunlight to produce glucose and oxygen, while cellular respiration uses glucose and oxygen to produce carbon dioxide, water, and energy in the form of ATP. Students are tasked with creating a poster comparing and contrasting photosynthesis and cellular respiration by including chemical formulas, drawings, and labeling reactants and products.

6 Inh Variation and Evolution.pptx
Here are the key steps in cloning plants:
1) Plants can reproduce asexually through processes like producing runners or stolons, which will grow into clones that are genetically identical to the parent plant.
2) For example, a spider plant grows a rooting side branch called a stolon that will become a clone of the parent plant. A gardener may also take cuttings from a desirable plant to grow into clones.
3) The clones are genetically identical to the original parent plant and are called clones. The only variation between clones will come from environmental factors, not genetic differences. Asexual reproduction produces clones while sexual reproduction produces offspring with genetic variation.

4 Bioenergetics KnowIT.pdf
Photosynthesis is the process by which plants produce glucose from carbon dioxide and water using energy from sunlight. The rate of photosynthesis is affected by several factors including carbon dioxide concentration, temperature, and light intensity, with each factor limiting the rate once a certain threshold is reached. Experiments can measure the rate of photosynthesis by counting oxygen bubbles produced over time as light intensity or other factors are varied.
6 inh variation evol knowit.pptx
Here are the key advantages summarized:
- Sexual reproduction leads to variation in offspring through meiosis and mixing of genes from two parents. This variation provides a survival advantage if the environment changes.
- Asexual reproduction requires only one parent so it is more efficient in terms of time, energy and resources as no mate needs to be found. However, offspring are identical clones with no genetic variation.
- Both types of reproduction have advantages depending on circumstances. Sexual reproduction promotes variation for changing environments while asexual is more efficient for stable conditions.
7 ecology knowit.pptx
The document discusses adaptations, interdependence and competition within ecological communities. It describes the different levels of ecological organization, including organisms, populations, communities, and ecosystems. Communities consist of many interacting populations that depend on each other through relationships like pollination, seed dispersal, and predator-prey interactions. Both biotic factors (living things) and abiotic factors (non-living things) influence communities. Organisms within communities compete for resources and adapt in ways that allow them to survive and reproduce under the prevailing environmental conditions. Competition and adaptations both help maintain a balanced community structure.
6.6 Hormones Homeo and Repro (Chris Paine)
Thyroxin is a hormone produced by the thyroid gland that controls metabolism and affects growth and physiological processes. It regulates the metabolic rate and helps control body temperature. Most hormones affect multiple target tissues and have more than one effect. The document discusses thyroid hormones and their roles, as well as hormones involved in the menstrual cycle and their feedback mechanisms.
6.5 neurons and synapses (chris paine)
The document discusses neurons and synapses in the human brain. It begins by showing an image of a small segment of the human brain, with lines representing neurons and dots representing synapses. It notes that synapses are crucial for neural communication and thought. While the number of brain cells does not increase much after birth, the connections between neurons through synapses continue developing. The document then provides explanations of key concepts regarding neurons, synapses, and neural signaling. It explains how neurons transmit electrical signals, how synapses allow signals to be transmitted between neurons, and how signals propagate along axons through action potentials.
6.4 Gas Exchange (Chris Paine)
The document discusses gas exchange in the lungs. It explains that two processes maintain concentration gradients of oxygen and carbon dioxide between the alveoli and blood: 1) circulation brings deoxygenated blood to the alveoli, and 2) ventilation increases and decreases lung volume through muscle contractions, ensuring a supply of oxygenated air reaches the alveoli. The diaphragm and intercostal muscles contract during inhalation to inflate the lungs, allowing for gas exchange by diffusion across the alveoli.
6.3 defence (chris paine)
The human body has structures and processes that resist the continuous threat of invasion by pathogens. These include leukocytes that ingest and destroy pathogens, as well as physical barriers like the skin and mucous membranes. The body also has mechanisms for blood clotting to prevent the entry of pathogens through cuts in the skin. Lymphocytes produce antibodies that provide specific immunity against particular pathogens. While antibiotics can treat bacterial infections by blocking bacterial processes, they are ineffective against viruses which lack metabolism and cannot be treated in the same way.
6.2 Blood System (Chris Paine)
The blood system continuously transports substances to cells and collects waste through three main types of blood vessels. Arteries carry blood away from the heart to tissues and have muscle and elastic fibers to maintain blood pressure. Capillaries have thin walls that penetrate tissues and allow for exchange. Veins collect blood from tissues and return it to the heart, using valves to prevent backflow. William Harvey discovered the circulation of blood in the early 1600s, overturning earlier theories, and the heart acts as a pump initiated by the sinoatrial node to circulate blood continuously through this system.
6.1 Digestion and Absorption (Chris Paine)
The small intestine has a structure that allows for both digestion and absorption of food. It has a folded inner wall and muscular outer layers that help move food along. The inner wall contains villi and microvilli that greatly increase the surface area for digestion and absorption. Enzymes in the small intestine digest macromolecules in food into smaller monomers. Absorption then occurs as these smaller molecules like glucose, amino acids, and fatty acids pass through the epithelial cells lining the villi into the bloodstream using various membrane transport processes. The liver plays an important role in processing absorbed glucose from the small intestine.
C ecology & conservation syllabus statements
The document discusses various topics relating to ecology and conservation, including species and communities, ecosystems, impacts of humans, conservation of biodiversity, population ecology, and nitrogen and phosphorus cycles. It provides essential ideas, understandings, applications, and skills for each topic. For example, for species and communities the essential idea is that community structure emerges from ecosystem properties, and understandings include how limiting factors affect species distribution and the unique role each species plays.
Academic honesty in ib
The document discusses academic honesty and misconduct in the International Baccalaureate (IB) program. It defines key terms like plagiarism, collusion, and exam misconduct. It notes that over half of investigated cases involve plagiarism while a quarter involve collusion. The document warns students about the consequences of getting caught cheating, like being banned from future exams or failing their diploma. It emphasizes that students are responsible for knowing what constitutes academic dishonesty and how to properly cite sources to avoid plagiarism.
Cas an introduction
This document provides information about CAS (Creativity, Activity, Service) which is an important component of the International Baccalaureate Diploma Programme. It explains that CAS involves learning through experience, personal development, and making a difference to others. Students must be involved in a variety of CAS experiences over 18 months including activities in creativity, activity, and service, as well as a CAS project and ongoing reflection. The document outlines examples of acceptable CAS experiences and provides guidance on documenting CAS in a portfolio using the learning outcomes framework.
11.2 muscle contraction
There are three main types of muscle tissue - skeletal, smooth, and cardiac. Muscle fibers are multinucleated cells formed from the fusion of individual embryonic muscle cells. Within each fiber are many parallel myofibrils composed of repeating sarcomere units. A sarcomere contains overlapping actin and myosin filaments. When an action potential reaches the neuromuscular junction, acetylcholine is released causing calcium ions to enter the fiber and allow the myosin heads to bind to actin, pulling the filaments together and contracting the muscle fiber. ATP provides energy to break the binding and reset the muscle for the next contraction.
