PPT-Electron Transport and ATP Synthesis

C483 Spring 2013 1 To reduce one molecule of O2 electrons must be passed through the electron transport chain and molecules of NADH isare oxidized A 4 2 B 2 1 C 1 1. Unit 3 . Think back to Energy Transfer…. Living things use energy for . Growth. Repair. Reproduction. Metabolism. The collection of reactions that occur in a cell . Metabolism. Involves either:. . The flow of electrons from NADH and FADH. 2. to O. 2. occurs in the electron-transport chain or respiratory chain.. This exergonic set of oxidation–reduction reactions generates a proton gradient.. Cellular respiration can best be described as. using energy released from breaking high-energy covalent bonds in organic molecules to force ATP formation from ADP and phosphate.. taking electrons from food and giving them to . Chapter 21 . Stryer. Short Course. Overview. Redox reactions. Electron transport chain. Proton gradient. ATP synthesis. Shuttles. Analogy: How does burning coal put flour in the grocery store?. Compartmentalization. Pages 213-220. Aerobic Cellular Respiration. Mitochondria. Round or sausage shaped organelle. Specialize in the production of large quantities of ATP. Site of aerobic cellular respiration. ATP production requires free oxygen. 3.3 Energy/Carbon Source Classes of Microorganisms-definitions. 3.4 Bioenergetics. 3.6 Electron Donors and Electron Acceptors. 3.7 Energy-Rich Compounds: ATP. Modes of .

Modes of . ATP . Synthesis. 3.3 Energy Classes of Microorganisms. Respiration can be considered the opposite process of photosynthesis. It is the transformation of food energy into chemical energy in the form of ATP. Plants and animals go through the same process of cellular respiration. What is respiration?. Respiration. is the process by which organisms extract the energy stored in complex molecules and use it to generate . adenosine triphosphate (ATP). .. ATP provides the immediate source of energy for biological processes such as active transport, movement and metabolism.. Oxidative Phosphorylation & the Electron Transport Chain. Energy from Reduced Fuels is Used to Synthesize ATP in Animals. Carbohydrates, lipids, and amino acids are the main . reduced fuels. for the cell.

Unlike most enzymes, product release is the rate-determining step for ATP synthase. 1. Cellular respiration. Cellular respiration and fermentation. Fermentation = An ATP-producing catabolic pathway in which both electron . donors . and . acceptors are organic compounds.. • Can be an anaerobic process. Respiration. Respiration is a catabolic pathway that is controlled by different enzymes.. It releases energy from a molecule of 6 carbon glucose by breaking it down into smaller, simpler molecules.. Respiration.
