Under anaerobic conditions, glycolysis provides most of the ATP that the cell needs. In animal cells, pyruvate, the end product of glycolysis, is converted to lactic acid by lactate dehydrogenase, as shown below:
CH3(CO)COO- + X ?CH3(CHOH)COO- + Y What is the correct carrier pair (in place of X and Y) in this reaction?
A) X is (ADP + Pi), and Y is (ATP) B) X is (NADP+), and Y is (NADPH + H+) C) X is (NAD+), and Y is (NADH + H+) D) X is (NADH + H+), and Y is (NAD+) E) X is (NADP++ H+), and Y is (NADPH)
