What is the net ATP yield of glycolysis from one glucose molecule?
Answer and explanation
Correct answer: B. 2 ATP
- Step 1: Glycolysis uses 2 ATP in the investment phase. Step 2. It makes 4 ATP in the payoff phase, so the net gain is 2. Answer: 2 ATP. Why not the others: 4 is the gross yield; 36 includes oxidative phosphorylation; zero ignores substrate-level phosphorylation.
