In aerobic metabolism, what is the fate of pyruvate produced by glycolysis?
A) Pyruvate loses carbon dioxide, and the remaining two carbon atoms become linked to coenzyme A.
B) Pyruvate loses carbon dioxide, producing acetaldehyde, which, in turn, is reduced to ethanol.
C) Pyruvate is reduced to lactate.
D) None of these
