Glyceraldehyde phosphate is oxidized during glycolysis. What happens to hydrogen atoms and the electrons that are removed during oxidation?
Correct answer: D. They reduce NAD+
- A. They reduce NADP
- B. They are transferred to pyruvic acid
- C. They are eliminated in the form of methane
- D. They reduce NAD+
Explanation
The hydrogen atoms and electrons removed during the oxidation of glyceraldehyde phosphate in glycolysis are used to reduce NAD to NADH. NADH is an important carrier of electrons that plays a role in subsequent energy-yielding reactions, particularly during oxidative phosphorylation.
