Detailed explanation-1: -Solution : During aerobic respiration, 38 ATP molecules are gained. If specifically aerobic respiration in eukaryote is asked, then the answer would be 36 ATP because 2 ATP molecules are produced by ‘FADH (2)‘ which accepts the ‘H(+)‘ from 2 NADH moleucles produced in glycolysis.

Detailed explanation-2: -Reason: There is net gain of 18 ATP molecules during aerobic respiration of one molecule of glucose.

Detailed explanation-3: -So, in aerobic respiration, a total of 38 molecules of ATP are created, with 2 ATP molecules formed outside the mitochondria. Electron transfer from glycolysis’ NADH and FADH2 molecules, pyruvate transformation, and the Krebs cycle generates up to 32 additional ATP molecules.

Detailed explanation-4: -In eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH.

Detailed explanation-5: -Cellular respiration produces 36 total ATP per molecule of glucose across three stages. We can describe each stage’s ATP production. The first stage, glycolysis, occurs in the cytosol and nets 2 ATP when splitting the six carbon glucose into two three-carbon fragments.
