Correct option (c) 36
Explanation:
The net gain from complete oxidation of a glucose molecule in aerobic respiration is 36 ATP molecules. 10 molecules of NADH2. (2 from Glycolysis + 8 from Krebs' cycle) yield = 10 x 3 = 30 ATP, 2 molecules of FADH2 yield
= 2 x 2 = 4 ATP and glycolysis also yields 2 ATP. Therefore, total release of ATP per hexose will be = 30 + 4 + 2 = 36 ATP.
