Substrate-level phosphorylation (a) occurs through a chemiosmotic mechanism (b) accounts for most of the ATP formed during aerobic cellular respiration (c) occurs during the conversion of pyruvate to acetyl CoA (d) occurs during glycolysis and the citric acid cycle (e) requires high energyelectrons from NADH
Which of the following metabolic process produces NADH or NADPH? And which process requires the reducing power of NADH or NADPH as a cofactor?
(1) Glycolysis(2) Gluconeogenesis(3) Pentose Phosphate Pathway(4) TCA cycle(5) Oxidative Phosphorylation(6) Catabolism of fatty acids(7) Anabolism of fatty acids

In one of the steps of glycolysis, the enzyme pyruvate kinase catalyzes the conversion of phosphoenolpyruvate to pyruvate; the phosphate group from phosphoenolpyruvate is transferred to ADP to
form ATP during the reaction. This process is an example of:
A) O ATP synthesis by substrate-level phosphorylation
B) O coupling an energy releasing process to an energy requiring process
C) O oxidative phosphorylation
D) OB and C are correct
E) OA and B are correct
