The document discusses key concepts in organic chemistry and biochemistry. It covers organic compounds, carbon bonding, polymers, macromolecules including carbohydrates, lipids, proteins and nucleic acids. It also discusses the structure and functions of enzymes.
Proteins - Edexcel A-Level Biology B Topic 1.2
This document discusses proteins and their structure. It notes that proteins make up 18% of the human body and are essential components of things like hair, skin, nails, enzymes, hormones, muscles and more. Proteins are composed of long chains of amino acids that join together via condensation reactions. There are 20 naturally occurring amino acids that can combine in various ways to form different proteins. The chains of amino acids fold into complex 3D structures held together by bonds like peptide bonds, hydrogen bonds, disulfide bonds, and ionic bonds. This intricate 3D structure allows proteins to perform their many vital functions in the body.
Amino acidsynthesis
This document discusses amino acid biosynthesis. It begins by explaining how diazotrophs fix atmospheric nitrogen into ammonia. It then describes the glutamate dehydrogenase and glutamine synthetase reactions, which are important in amino acid synthesis. The document notes that preformed alpha-amino nitrogen in the form of glutamate must be considered an essential nutrient. It lists the essential and nonessential amino acids, and explains how nonessential amino acids are synthesized from common metabolic intermediates like pyruvate, oxaloacetate, and alpha-ketoglutarate using transamination reactions. The role of tetrahydrofolate in transferring single carbon units for metabolic precursors is also summarized.
Biol161 02
The document discusses the key biomolecules found in living things including proteins, carbohydrates, lipids, and nucleic acids. It describes the basic monomers like amino acids and nucleotides that make up these biomolecules, and how they are linked together through peptide bonds in proteins or phosphodiester bonds in nucleic acids. It also provides examples of specific biomolecules like collagen, hemoglobin, and fatty acids to illustrate their structures and functions.
Lipids - Edexcel A-Level Biology B Topic 1.2
Lipids are a group of organic molecules that play vital roles in organisms. They form integral parts of all cell membranes and are also used as an energy store. Fats and oils are important lipids that contain fatty acids and glycerol bonded together by ester bonds. Fats are solid at room temperature while oils are liquid. Phospholipids also contain fatty acids but have a phosphate group instead of a second fatty acid. Phospholipids form bilayer structures in cell membranes with their hydrophilic heads facing out and hydrophobic tails in the middle. This bilayer structure is the basis of all biological membranes.

Bioenergética i
The document discusses the mechanism of aggregation of amyloid beta monomers to form amyloid fibrils. It states that monomers first aggregate to form a high-energy nucleus of a few chains, represented by a hexagonal arrangement. Once this nucleus is formed, aggregation proceeds energetically downhill to create the amyloid fibril. However, the structure of the nucleus and the steps between unstructured monomers and amyloid form are still unknown.

Nucleotides
This document discusses nucleotides and their importance. Nucleotides serve as the principal donors and acceptors of phosphoryl groups in cellular metabolism and are the energy currency. They are also structural components of cofactors like vitamins. Nucleotides constitute nucleic acids DNA and RNA. Synthetic nucleotide analogs are used in chemotherapy to treat cancer and hyperuricemia. Nucleotides have diverse physiological functions and absorb ultraviolet light. They are polyfunctional acids and nucleoside triphosphates have high group transfer potential.
Bio packet
1) Beadle and Tatum conducted experiments with Neurospora that provided early evidence for the central dogma. They found that mutations in specific genes prevented the production of enzymes needed to synthesize vitamins and amino acids, disrupting growth.
2) Their experiments demonstrated that each step in biochemical pathways, like the conversion of precursors to arginine, requires a specific gene to produce the corresponding enzyme. This supported the idea that one gene encodes for one enzyme.
3) Fireflies produce light through a process where the luciferase enzyme binds to luciferin and speeds up a reaction that produces light. The light serves to attract mates and warn predators, who associate the glow with the firefly's bad
B2-3.2 factors affecting enzyme action
Enzymes are biological catalysts that speed up chemical reactions in the body. They are made of proteins and have a specific 3D shape that allows only certain substrate molecules to bind to their active site. This locks the substrate in place and facilitates a reaction without using up the enzyme. For example, the enzyme catalase speeds up the breakdown of toxic hydrogen peroxide into harmless oxygen and water molecules.

Cellular respiration involves four stages to harvest energy from glucose and produce ATP. In the first stage, glycolysis, glucose is broken down without oxygen to form pyruvate. The next two stages, pyruvate oxidation and the Krebs cycle, occur in the mitochondria using oxygen. In these stages, electrons are transferred to electron carriers like NADH and FADH2. In the final stage, the electron transport chain, the electron carriers donate their electrons to oxygen and protons are pumped across the membrane. This creates a proton gradient that is used by ATP synthase to phosphorylate ADP and produce ATP. The overall process of cellular respiration oxidizes glucose and reduces oxygen to produce carbon dioxide, water, and ATP

The document discusses chemical tests for biological molecules like carbohydrates, proteins, lipids, and nucleic acids. It describes the basic structure of DNA as a double helix consisting of nucleotides with phosphate, sugar, and nitrogenous base components. DNA contains the genetic instructions for life and encodes hereditary information through its sequence of nucleotide base pairs between strands. RNA is similar to DNA but is usually single-stranded and found in the nucleus.
Atp Teach Intro
1) Organisms require energy to carry out essential life functions like building biomolecules, reproduction, movement, and temperature regulation.
2) Cells obtain this energy through catabolic reactions that break down organic molecules from food, capturing the released energy in ATP.
3) ATP is an efficient way to store and transport energy within cells through its high-energy phosphate bonds, which are unstable and easily broken to fuel other energy-requiring cellular processes.
Cell Respiration
Metabolism involves the chemical processes that take place in organisms. There are catabolic pathways that break down molecules and release energy, and anabolic pathways that use energy to build molecules. Energy exists in different forms like kinetic and potential energy, and transformations are governed by thermodynamics laws. Cellular respiration uses energy from food molecules and involves glycolysis, breakdown of pyruvic acid, the citric acid cycle, and the electron transport chain, requiring oxygen. Without oxygen, anaerobic respiration like lactic acid fermentation allows glycolysis to continue to produce ATP.
Biomolecules
The document provides an introduction to macromolecules (biomolecules) that make up living things. It discusses the four main types of organic macromolecules: carbohydrates, lipids, proteins, and nucleic acids. It describes the monomers (single units) that combine to form polymers (long chains) of each macromolecule, including examples like glucose and fatty acids.
07 energy
The document discusses how cells obtain and store energy. Cells use photosynthesis or respiration to meet their energy needs. Photosynthesis uses sunlight to produce sugars and oxygen from carbon dioxide and water, storing energy in the bonds of glucose. Respiration breaks down glucose to release energy, producing carbon dioxide and water. The energy is stored in ATP molecules through bonding phosphate groups. Cells need ATP for processes like active transport, cell division, and protein production.
Macromolecules scf 1.4.1
Macromolecules are large organic molecules that are made up of smaller building blocks called monomers. There are four main types of macromolecules: carbohydrates, lipids, proteins, and nucleic acids. Macromolecules are formed through dehydration synthesis which combines monomers, and they are broken down through hydrolysis which separates monomers by adding water.
Chemistry of nucleotides
- Nucleotides are composed of a nitrogenous base (purine or pyrimidine), a pentose sugar (ribose or deoxyribose), and one or more phosphate groups. When a base combines with a sugar, a nucleoside is formed. The addition of phosphate groups forms nucleotides.
- The four bases found in nucleic acids are adenine, guanine, cytosine, and either thymine in DNA or uracil in RNA. These bases combine with either ribose or deoxyribose to form nucleosides like AMP, GMP, CMP, TMP, or UMP.
- Nucleotides are the monomers that make up nucleic acids DNA and RNA
Unit 6 dna powerpoint(revised2006)
The document discusses the process of DNA replication in cells. It begins by reviewing that DNA is found in the nucleus and stores the cell's genetic information. It then describes in three steps how DNA replicates: 1) The DNA helicase enzyme unwinds the double helix, 2) DNA polymerase adds complementary nucleotides to each strand, and 3) DNA ligase seals the phosphate backbone. The document emphasizes that DNA replication is essential for cells to divide and for organisms to grow and develop.
Nucleic Acid Chemistry session one-1.ppt
This document provides information about nucleic acids and their structure. It discusses that nucleic acids are polymers made up of nucleotides that store and transmit genetic information. There are two main types of nucleic acids - DNA and RNA. A nucleotide is composed of a nitrogenous base, a pentose sugar (ribose in RNA and deoxyribose in DNA), and a phosphate group. The nitrogen bases in nucleotides can be purines (adenine and guanine) or pyrimidines (cytosine, thymine, and uracil). DNA has a double-stranded helical structure, with complementary base pairing between adenine-thymine and guanine-cytosine. RNA is typically single-stranded. ATP

Q4_LESSON 1_ATP.pptx
The document summarizes ATP (adenosine triphosphate), the molecule that transfers energy within cells. It describes ATP's structure of adenine, ribose, and three phosphate groups. ATP is generated through cellular respiration breaking down glucose and lipids from food. Energy is stored in ATP's bonds and released when a phosphate is removed, converting ATP to ADP (adenosine diphosphate). The cycle is recharged as ADP regains a phosphate with energy from cellular respiration to reform ATP. ATP powers various cellular functions and transports molecules before being broken down again.
DNA
The document discusses DNA structure and replication. It describes nucleotides as the building blocks of DNA, composed of a nitrogenous base, 5-carbon sugar (deoxyribose), and phosphate group. The 4 nitrogenous bases in DNA - adenine, thymine, cytosine, guanine - pair up in specific ways. DNA replication involves unwinding the DNA double helix, breaking the hydrogen bonds between bases, and using each original strand as a template to build a new complementary strand, resulting in two new DNA molecules each with one original and one new strand - known as semi-conservative replication.
Nucleic Acids
The document discusses the chemical composition and structure of nucleic acids. There are two main types of nucleic acids - DNA and RNA. Both are composed of nucleotides, which contain a phosphate group, a sugar (ribose in RNA, deoxyribose in DNA), and a nitrogenous base. DNA forms a double helix structure in the nucleus and stores genetic information. RNA is single-stranded and found in the nucleus and cytoplasm, assisting with protein synthesis through messenger RNA, transfer RNA and ribosomal RNA.

ATP_ppt.pptx
ATP is the molecule that transfers energy within cells through the addition and removal of phosphate groups. ATP is formed through cellular respiration as food molecules are broken down. When a phosphate is removed from ATP, it becomes ADP and energy is released for cellular processes. ADP can then regain a phosphate through energy input to reform ATP. This ATP-ADP cycle allows the cell to constantly store and provide energy for functions.
What is an ATP
1. Adenosine triphosphate (ATP) is composed of adenine, ribose sugar, and three phosphate groups. It acts as the main energy currency in cells.
2. ATP stores and transports chemical energy within cells by breaking its high-energy phosphate bonds. When a cell needs energy, it hydrolyzes ATP to ADP, releasing energy. Excess energy is stored by reforming ATP from ADP and phosphate.
3. ATP is uniquely suited to act as the primary energy carrier in cells. Its high-energy bonds are unstable and readily broken to fuel cellular reactions, then reformed when energy is available. This allows ATP to efficiently provide short-term energy storage and transport.

2. ATP stores and transports chemical energy within cells by breaking its high-energy phosphate bonds. When a cell needs energy, it hydrolyzes ATP to ADP, releasing energy. Excess energy is stored by reforming ATP from ADP and phosphate.
3. ATP is uniquely suited to act as the primary energy carrier in cells. Its high-energy bonds are unstable and readily broken to fuel cellular reactions, then reformed when energy is available. This allows ATP to efficiently provide short-term energy storage and transport.

BiologicalReview29_4_ATP_Presentation (1).pptx
This document discusses ATP (adenosine triphosphate), including its structure, importance, and how it is made. ATP is an important energy carrier in cells that contains adenine, ribose, and three phosphate groups. It is produced through substrate-level phosphorylation during glycolysis and the Krebs cycle. Most ATP is made through oxidative phosphorylation in the mitochondria during cellular respiration, as well as through photophosphorylation in the chloroplasts during photosynthesis. Both processes use chemiosmosis and ATP synthase to produce ATP from ADP and inorganic phosphate using energy released from electron transport chains.
nucleic acids 2012.ppt
The document discusses nucleic acids and their role in storing and transmitting genetic information. It describes that nucleic acids are made up of nucleotides, which consist of a nitrogen base, a 5-carbon sugar (ribose in RNA, deoxyribose in DNA), and a phosphate group. Nucleic acids include RNA and DNA, with DNA being a double-stranded polymer and RNA typically being single-stranded. The nitrogen bases in DNA and RNA form complementary base pairs (A-T and C-G in DNA, A-U and C-G in RNA) that allow the polymers to take on their helical structures. Genetic information is encoded in the sequence of bases in nucleic acids.

Nucleic acids include RNA and DNA, with DNA being a double-stranded molecule that stores genetic information in the form of genes. The complementary base pairs that bind the two DNA strands together are adenine-thymine and cytosine-guanine.
Nucleotide
This document discusses nucleotide chemistry. Nucleotides are organic compounds composed of a phosphate group, nitrogenous base, and a sugar molecule. They serve as the building blocks of nucleic acids DNA and RNA. Nucleotides also function as sources of chemical energy through molecules like ATP and GTP, and participate in cellular signaling through molecules like cAMP and cGMP. The document goes on to describe the specific sugars, bases, nucleosides, and nucleotides that make up DNA and RNA. It provides details on nucleotide nomenclature and classification and discusses important adenosine-containing nucleotides and their roles, such as ATP serving as an important energy source in many cellular processes.

Nucleic acids
DNA and RNA are nucleic acids that store and help express genetic information. DNA is composed of nucleotides containing deoxyribose, phosphates, and one of four nitrogenous bases (adenine, guanine, cytosine, thymine). RNA is similar but contains ribose and uracil instead of thymine. The genetic code is stored in DNA as base pair sequences in chromosomes. During cell division, DNA replicates and genes direct protein production through transcription of DNA to mRNA and translation of mRNA to proteins.

Chapter 11 [blood abnormalities n diseases]
This document summarizes various blood abnormalities and diseases including anemia, thalassemia, sickle cell anemia, and hemophilia. It discusses how anemia can be caused by a decrease in red blood cells due to hemorrhaging, lysis, or diseases like leukemia, or due to not enough hemoglobin from lack of iron or conditions like thalassemia. Thalassemia is an inherited disorder that causes the body to make fewer healthy red blood cells and less hemoglobin. Sickle cell anemia causes red blood cells to become sickle-shaped. Hemophilia is a bleeding disorder where individuals have little or no clotting factor, with the two main types being Hemophilia A

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

- 2. Proteins: a closer look Structural Levels of Proteins Primary Structure- The Amino Acid sequence of the peptide chain, held together by covalent bonds Secondary Structure- Alpha Helix’s and Beta sheets, held together by hydrogen bonds Tertiary Structure – 3D structure of a SINGLE protein molecule, completely compacted and folded polypeptide chain, held together by Disulfide bonds and Ionic bonds Quaternary Structure- A Complex built of several protein molecules or polypeptide chains (sub-units), bound together by Covalent bonds and Disulfide bridges
- 3. Proteins: Denaturing What is Denaturing ? Simply put it is when a Protein Complex comes apart due to acid, alkali or heat Ex. Cooking an EGG What happens to a Protein that is Denatured? Biologically: its original properties are diminished or rendered completely useless Physically: It loses it’s “useful” shape. i.e. It ~unravels~
- 5. Proteins: Enzymes Many Enzymes/Catalysts must be “ACTIVATED” before they can be useful Ex. Phosphorylation ( Meaning simply: The addition of phosphate to an organic compound .) The “Active Site” is part on the enzyme that the substrate binds to. There’s WAY more to enzymes than this but… We’ll Keep it Simple ACTIVE ENZYME~POOF~
