alleryThe net energy yield of glycolysis per glucose is
A4 ATP and 4 NADH, but 0 pyruvate
Bthe full 36 ATP and 6 NADH per glucose
C0 ATP since glycolysis is purely preparatory
D2 ATP and 2 NADH, plus 2 pyruvate
Answer & Solution
Correct answer: D. 2 ATP and 2 NADH, plus 2 pyruvate
Glycolysis spends 2 ATP in the investment phase and earns 4 ATP in the payoff phase, so net = 2 ATP.
It also makes 2 NADH (one per 3-carbon half) and yields 2 pyruvate.
The 36-ATP figure is for the full aerobic pathway.
