Question

What is the net gain in Krebs cycle? (1)1 FADH,,2 NADH,and 1 ATP (2)2 FADH,,2 NADH,and 2 ATP (3)1FADH,,3 NADH,and 1 ATP (4)1 FADH,,6 NADH,and 2 ATP

Answer 1

Because NADH started with Complex I, it had more chances to pumps more protons across the gradient, which powers the ATP synthase and gives us 3 ATP per molecule of NADH. FADH2 produces 2 ATP during the ETC because it gives up its electron to Complex II, bypassing Complex I.

Answer 2
