  1. Question 1

    Q1. During the link reaction (pyruvate oxidation), pyruvate is converted into Acetyl-CoA. What is the net yield of reduced coenzymes per molecule of pyruvate oxidized?

    • A) Two FADH2
    • B) One ATP
    • C) One NADH
    • D) Two ATP

    Answer: One NADH

    Explanation: The oxidation of one pyruvate to Acetyl-CoA produces one NADH; since two pyruvates are formed per glucose, two NADH are produced globally.
