Concept 9.1 -- Catabolic pathways yield energy by oxidizing organic fuels.•Process of electron transport chain. •Analogous “downhill” route of ETC (the e- removedfrom glucoseby NADHis pulled toward oxygenfor stability) Concept 9.2 -- Glycolysis harvests chemical energy by oxidizing glucose to pyruvate•Define: Glycolysis (The splitting of glucoseinto pyruvate.)•Define Citric Acid Cycle (completes the breakdown of glucoseby oxidizinga derivative of pyruvateto 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 CO2is released during glycolysis.
