Question

During the citric acid cycle, both NAD and FAD ________ a hydrogen atom and become ________.
A) lose; oxidized
B) gain; oxidized
C) lose; reduced
D) gain; reduced
E) gain; ATP

Accepted Answer

During the citric acid cycle, both NAD+ and FAD act as electron acceptors. They gain a hydrogen atom (and its electron) and become reduced to NADH and FADH2, respectively. This process is part of cellular respiration where energy is produced in the form of ATP.
