- A 2 molecules of pyruvic acid
- B 1 molecule of CO2
- C 2 molecules of glucose
- D Acetyl CoA directly
Correct answer: A. 2 molecules of pyruvic acid
Explanation: Glycolysis splits one 6-carbon glucose into 2 molecules of 3-carbon pyruvic acid, with a net gain of 2 ATP and 2 NADH.
Concept context
Glycolysis, the Krebs cycle, the electron transport chain, fermentation, and the respiratory quotient. The cellular energy-release counterpart to photosynthesis.
