Question
Which coenzyme is reduced during the Krebs cycle and donates electrons to the ETC?
Correct Answer
Option C is the correct answer.
Detailed Explanation
NAD+ is reduced to NADH during the oxidation reactions of the Krebs cycle (and glycolysis). NADH then donates its high-energy electrons to the electron transport chain (ETC) at Complex I.
