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
