During the Krebs cycle, most high-energy electrons are captured by NAD+. At which specific step is FAD reduced to FADH2 instead?
Q1. During the Krebs cycle, most high-energy electrons are captured by NAD+. At which specific step is FAD reduced to FADH2 instead?
Answer: Succinate to fumarate
Explanation: Succinate dehydrogenase reduces FAD to FADH2 during the conversion of succinate to fumarate. Malate to oxaloacetate produces NADH.
