During one turn of the Krebs cycle, how many molecules of NADH are produced per acetyl-CoA that enters the cycle?

Core Concept

One turn of the Krebs cycle produces 3 NADH per acetyl-CoA: one when isocitrate is oxidized to alpha-ketoglutarate, one when alpha-ketoglutarate is oxidized to succinyl-CoA, and one when malate is oxidized to oxaloacetate.
