Chapter 9: Redux When oxygen becomes H2O, it is reduced because electrons of covalent bond spend more time near oxygen o Electron loses potential energy when it moves from a less electronegative atom to a more electronegative one, energy is released Dehydrogenase- removes 2 H and 2 e from a substrate, oxidizing it, for NAD+ The Processes Glycolysis [Net Yield: 2 ATP, 2 NADH] Glucose is split into 3-C sugars, which are oxidized and remaining molecules arranged to form pyruvate Energy investment and energy payoff phase Citric Acid Cycle [Net Yield: 2 ATP, 2 FADH2, 6 NADH, 4 CO2] Pyruvate enters mitochondrion via transport protein Dehydrogenase complex hydrolyzes the following three steps Carboxyl removed from pyruvate, released as CO2 Remaining 2-C fragment is oxidized (NADH formed) and forms acetate Coenzyme A attached, forms acetyl coA (very reactive) Acetyl group of coA will enter citric acid cycle, adding oxaloacetate makes citrate, cycle 1 ATP, coA, 1 FADH2, 3 NADH, 2 CO2 per acetyl
