Single correct option

The net gain of ATP molecules per glucose molecule in glycolysis is
  1. A. 4
  2. B. 36
  3. C. 38
  4. D. 2
Show answer and solution

Answer: (D) 2

Glycolysis, occurring in the cytoplasm, produces 4 ATP and uses 2 ATP, giving a net gain of 2 ATP per glucose along with 2 NADH and 2 pyruvate. The values 36 or 38 are the approximate yields for complete aerobic respiration. The number 4 is the gross yield and ignores the 2 ATP spent.
