The most abundant acceptor for hydrogen released in the Krebs cycle is A)TPN. B)NADP⁺. C)NAD⁺. D)FAD. E)cytochrome oxidase.

Question

Quizplus · Accepted Answer

The most abundant acceptor for hydrogen released in the Krebs cycle is NAD+ (nicotinamide adenine dinucleotide). Option C, NADP+ (nicotinamide adenine dinucleotide phosphate), is also a viable choice as it is a closely related molecule that can also act as a hydrogen acceptor. However, the answer choices A, D, and E are not involved in the electron transport chain following the Krebs cycle, and so they are not the most abundant acceptors for hydrogen released in the cycle.
