Which of the following statements about NAD+ is true?

Which of the following statements about NAD+ is true?

a. NAD+ has more chemical energy than NADH.

b. NAD+ is reduced to NADH during glycolysis, pyruvate oxidation, and the citric acid cycle

c. NAD+ is oxidized by the action of hydrogenases.

d. NAD can donate electrons for use in oxidative phosphorylation.

The correct answer is (b) NAD+ is reduced to NADH during glycolysis, pyruvate oxidation, and the citric acid cycle

NADH

NADH is an electron carrier used in the process of cellular respiration. The oxidized form, NAD+, receives electrons from glucose, forming NADH. NADH then carries these electrons to the electron transport chain, where they can be used to generate ATP.
