Which electron carrier(s) function in the citric acid cycle?
A) NAD+ only
B) NADH and FADH2
C) the electron transport chain
D) ADP and ATP

Question

Quizplus · Accepted Answer

NADH and FADH2 are electron carriers that function in the citric acid cycle by donating electrons to the electron transport chain, which generates ATP through oxidative phosphorylation. NAD+ is not an electron carrier in the citric acid cycle, and ADP and ATP are not electron carriers but rather molecules involved in energy transfer. The electron transport chain is also involved in generating ATP but is not directly involved in the citric acid cycle.
