Show Answer

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.
