During strictly anaerobic exercise, muscle cells preferentially:

C) decarboxylate pyruvate to acetaldehyde.
D) reduce pyruvate to lactate.
E) none of the above.

Question

Quizplus · Accepted Answer

During strictly anaerobic exercise, muscle cells preferentially reduce pyruvate to lactate through the process of anaerobic glycolysis. This allows for the production of ATP without the need for oxygen, as oxygen is not present in a sufficient amount to support aerobic respiration.
