Question

The net gain of ATP molecules during aerobic breakdown of one glucose molecule is  (A) 40 (B) 38 (C) 36 (D) 30

Tardigrade Admin · Accepted Answer

There is net gain of 38 ATP molecules during aerobic respiration of one molecule of glucose. But in most eukaryotic cells, 2 molecules of ATP are required for transporting the NADH produced in glycolysis into the mitochondrion for further oxidation. Hence, net gain of ATP here is 36 molecules.
