Which of the Following Statements Best Describes a Characteristic of NAD

Question

Which of the following statements best describes a characteristic of NAD+?
A) NAD+ is reduced to NADH in glycolysis, pyruvate oxidation, and the citric acid cycle.
B) NAD+ stores more chemical energy than NADH.
C) NAD+ may donate electrons for use in oxidative phosphorylation.
D) NAD+ is oxidized in glycolysis to produce ATP.

Accepted Answer

NAD+ is reduced to NADH during glycolysis, pyruvate oxidation, and the citric acid cycle, acting as an electron carrier by accepting electrons and becoming NADH. This process is crucial for cellular respiration and energy production in cells.
