Concept 9.1 -- Catabolic pathways yield energy by oxidizing organic fuels. Process of electron transport chain. Analogous “downhill” route of ETC (the e- removed from glucose by NADH is pulled toward oxygen for stability ) Concept 9.2 -- Glycolysis harvests chemical energy by oxidizing glucose to pyruvate Define: Glycolysis (The splitting of glucose into pyruvate .) Define Citric Acid Cycle (completes the breakdown of glucose by oxidizing a derivative of pyruvate to carbon dioxide .) Define: Oxidative Phosphorylation (Oxidative phosphorylation accounts for almost 90% of the ATP generated by respiration.) Define: Substrate–level phosphorylation For each molecule of glucose degraded to carbon dioxide and water by respiration, the cell makes up to about 38 molecules of ATP. Glycolysis divided into two phases: Energy investment & Energy payoff. The carbon originally present in glucose is accounted for in the two molecules of pyruvate; no CO 2 is released during glycolysis. Glycolysis occurs whether or not
