Which of these is a catabolic pathway that generates reducing equivalents (NADH, FADH2) and feeds electrons into the electron transport chain?
Show answer and explanation
Correct answer: Citric acid cycle (TCA cycle)
The citric acid cycle oxidizes acetyl-CoA to CO₂ and in the process produces NADH and FADH₂, which serve as electron donors for the electron transport chain and thereby drive ATP production.
