I. Aerobic respiration overview: a. generation of high energy molecules to power cellular processes i. NADH, FADH2—electron carriers/coenzymes in reduced form ii. NAD+, FAD+--electron acceptors/coenzymes in oxidized state iii. ATP—energy in phosphoanhydride bonds used to power other reactions b. Oxidation of glucose to CO2 c. Reduction of (atmospheric) O2 to H2O i. OIL RIG: oxidation is loss (of e-/H), reduction is gain (of e-/H) II. Oxidation of glucose a. Glycolysis i. Enzymes/rxns in cytoplasm ii. 6-C sugar is converted into 2 3-C compound (i.e. pyruvate), so no CO2 yet iii. Little ATP and NADH produced iv. Can operate in the presence or absence of oxygen 1. if no O2 present in cell a. fermentation/anaerobic respiration i. NAD+ is regenerated after NADH reduces pyruvate to lactic acid ii. Glycolysis can continue because there is NAD+ present to accept H from glucose 2. if O2 is around a. aerobic respiration will be occurring i. NADH will reduce ETC complexes ii. Pyruvate will not be converted to lactic acid
