Question: how many molecules of atp are produced from pyruvate oxidation?
Answer: Hopefully you are still awake at this point. Note that this process completely oxidizes 1 molecule of pyruvate, a 3 carbon organic acid, to 3 molecules of CO2. During this process, 4 molecules of NADH, 1 molecule of FADH2, and 1 molecule of GTP (or ATP) are produced.
