The net gain ATP from complete oxidation of 1 molecule of glucose in eukaryote is

  • 2

  • 4

  • 24

  • 36


D.

36

There is a total gain of 38 ATP molecules during aerobic respiration. Out of these two molecules of ATP, two are required for transporting the NADH produced in glycolysis (in cytoplasm) into the mitochondria for further oxidation, hence the net gain of ATP is 36 molecules.
