The end product of glycolysis is
- A. lactic acid
- B. pyruvic acid
- C. acetyl CoA
- D. citric acid
Explanation
Glycolysis splits the six carbon glucose into two three carbon molecules of pyruvic acid, and what happens next depends on whether oxygen is available. Lactic acid is formed only afterwards, in anaerobic conditions in muscle, and acetyl CoA only afterwards in the link reaction inside the mitochondrion. Citric acid is the first product of the Krebs cycle, two stages later.
