A) ATP.

D) coenzyme A

Quizplus · Accepted Answer

The immediate electron acceptor in most of the citric acid cycle reactions is NAD, which is reduced to NADH. In a few reactions, FAD is the electron acceptor instead, but NADH is the primary electron carrier. ATP is not an electron acceptor, but a source of energy, and coenzyme A is an acyl carrier, not an electron acceptor.
