Which of the following choices lists two electron carriers in their reduced forms?

A. NAD+ and FAD
B. NADH and FADH2
C. NAD+ and FADH2
D. NADH and FAD

Click for Explanation

B is correct. The reduced form of these two electron carriers are NADH and FADH2. Remember, reduction often involves the gain of bonds to hydrogen, and it always involves a decrease in oxidation state. In contrast, the oxidized forms are NAD+ and FAD.
