Respiration Energy Currency ATP the primary energy currency of the cell is produced through cellular respiration Redox Reactions Cellular respiration involves a series of redox reactions where electrons are transferred from glucose to oxygen releasing energy Cellular Respiration Equation C6H12O6 6O2 6CO2 6H2O Energy ATP 2 Glycolysis Breakdown of Glucose Glycolysis occurs in the cytoplasm and breaks down glucose into pyruvate generating a small amount of ATP and NADH Investment Phase The initial steps require ATP to activate glucose Payoff Phase The latter steps generate ATP and NADH with a net gain of 2 ATP and 2 NADH per glucose molecule 3 The Krebs Cycle Citric Acid Cycle Pyruvate Oxidation Pyruvate enters the mitochondria and is converted to acetylCoA releasing carbon dioxide and NADH Citric Acid Cycle Reactions AcetylCoA enters a cyclic series of reactions generating ATP 3 NADH FADH2 and carbon dioxide Central Hub of Metabolism The Krebs Cycle connects to other metabolic pathways linking carbohydrate fat and protein metabolism 4 Electron Transport Chain and Oxidative Phosphorylation Electron Carriers NADH and FADH2 deliver electrons to the ETC located in the inner mitochondrial membrane Proton Gradient As electrons move through the ETC protons are pumped across the membrane creating a proton gradient ATP Synthase This protein complex utilizes the proton gradient to drive ATP synthesis a process called oxidative phosphorylation 5 Anaerobic Respiration and Fermentation Absence of Oxygen In the absence of oxygen cells can still generate ATP through anaerobic respiration or fermentation Lactic Acid Fermentation Pyruvate is reduced to lactate producing a small amount of ATP Alcoholic Fermentation Pyruvate is converted to ethanol and carbon dioxide also producing a small amount of ATP 6 Regulation of Cellular Respiration Feedback Inhibition The product of a pathway can inhibit its own production ensuring efficient resource allocation Allosteric Regulation Enzymes can be activated or inhibited by molecules binding to sites other than the active site Hormonal Control Hormones like insulin and glucagon regulate cellular respiration to meet the bodys energy needs 7 Connections to Other Biological Processes Photosynthesis Cellular respiration is the complementary process to photosynthesis using the products of photosynthesis glucose and oxygen to generate energy Metabolism Cellular respiration is a key component of metabolism the sum of all chemical reactions in the body Cellular Growth and Development Cellular respiration provides
