Answer:
Correct Answer: D
Solution:
Under aerobic conditions, the products are pyruvate and coenzyme NADH.
Pyruvate directly enters the mitochondrial matrix and is converted into acetyl-CoA.
Under anaerobic conditions, pyruvate is used as a hydrogen acceptor and converted into lactate.
In anaerobic conditions, pyruvate remains in the cytosol.
