DENDROLOGY

Detailed explanation-1: -In aerobic respiration, the full oxidation of one glucose molecule can theoretically yield 38 ATP molecules.

Detailed explanation-2: -Explanation for Correct option: The citric acid cycle produces 36 ATP molecules. So, in aerobic respiration, a total of 38 molecules of ATP are created, with 2 ATP molecules formed outside the mitochondria.

Detailed explanation-3: -This process occurs through the breakdown of one molecule of glucose. Here the ATP molecules first form in the cytoplasm through glycolysis and then it is moved to the inner mitochondrial membranes where it produces 36 ATP molecules. Thus, the total ATP molecules produced are 38.

Detailed explanation-4: -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-5: -There are 38 ATP molecules produced in aerobic respiration all together, and 2 ATPs are formed outside the mitochondria. Note: For the use of glucose energy, fermentation is less efficient: only 2 ATP per glucose is produced, as opposed to 38 ATP per glucose nominally produced by aerobic respiration.
