Question

the nadh produced during glycolysis will be used in
multiple choice
pyruvate oxidation
the electron transport chain.
substrate - level phosphorylation
the krebs cycle.

Explanation:

1. Analyze each option:

• Pyruvate oxidation: Pyruvate oxidation uses pyruvate (from glycolysis) and produces NADH, not using the NADH from glycolysis.
• The electron transport chain: NADH (including that from glycolysis) donates electrons to the electron transport chain, which is used to generate ATP via oxidative phosphorylation.
• Substrate - level phosphorylation: This is a process of ATP generation that occurs in glycolysis and the Krebs cycle, and it does not use NADH.
• The Krebs cycle: The Krebs cycle uses acetyl - CoA (from pyruvate oxidation) and produces NADH, not using the NADH from glycolysis.

Answer:

B. the electron transport chain.
