Explanation:
Detailed explanation-1: -In aerobic respiration, the full oxidation of one glucose molecule can theoretically yield 38 ATP molecules. This is only an assumption because all of the routes are active at the same time, i.e., ATP and carbohydrates are used as necessary, and enzyme activity is controlled by various factors.
Detailed explanation-2: -According to some newer sources, the ATP yield during aerobic respiration is not 36–38, but only about 30–32 ATP molecules / 1 molecule of glucose, because: ATP : NADH+H+ and ATP : FADH2 ratios during the oxidative phosphorylation appear to be not 3 and 2, but 2.5 and 1.5 respectively.
Detailed explanation-3: -One ATP provides 7.3 kcal energy. Therefore, 38 ATP yields 227.4 Kcal energy.
