<prompt> Per TCA with 3 NADH and 1 FADH2, generates how many ATP?691215  <response>: Ans. is b i.e., 9One NADH produces 2.5 ATP and one FADH2 produces 1.5 ATP. Thus 3 NADH and 1 FADH2 will produce 9 ATP.There is production of ATP at substrate level also, Thus total 10 ATP molecules are produced per cycle.
