The Two Most Important Coenzymes for Glycolysis and the Citric

Question

The two most important coenzymes for glycolysis and the citric acid cycle are
A) ATP and ADP.
B) FAD and FMN.
C) NAD and ATP.
D) NAD and FAD.
E) ATP and GTP.

Accepted Answer

The two most important coenzymes for glycolysis and the citric acid cycle are NAD (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide). NAD is involved in the metabolism of glucose, while FAD is involved in the electron transport chain during oxidative phosphorylation. ATP (adenosine triphosphate) is also important in these processes, but it is not a coenzyme. Therefore, choices A, C, and E are incorrect. FAD and FMN (flavin mononucleotide) are similar but FMN is not as important in glycolysis as FAD. Therefore, choice B is incorrect.
