Approx 34 molecules is correct answer.
The net ATP gain from one glucose molecule in aerobic respiration is 38 ATP. It includes ATP produced in glycolysis, link reaction, TCA cycle and by oxidative phosphorylation in the electron transport system from oxidising NADH and FADH2, which produces 3 ATP and 2 ATP, respectively. Hence, during the complete oxidation of one molecule of glucose, 38 molecules of ATP are produced.
