A.
(c) Net gain of ATP during aerobic respiration
1.Glycolysis provides 2ATP molecules and 2NADH+H^+
2.Pyruvate oxidation yields 2NADH + H^+
3.Krebs’ cycle produces 2GTP molecules, 6NADH + H^+ and 2FADH_2 molecules.
4.In electron transport system one NADH + H^+ produce 3ATP and FADH2 produces 32 or 34 ATP.
2ATP from glycolysis + 2GTP from TCA cycle and 32/34 ATP
from ETS/ETC =38/36 ATP molecule.
