In exercising muscle with inadequate oxygen, pyruvic acid is reduced to:
ALinoleic acid
BLactic acid
CLauric acid
DLipoic acid
Answer & Solution
Correct answer: B. Lactic acid
1. The muscle cannot wait for oxygen to arrive.
2. It takes the same route as certain bacteria.
3. In muscles during exercise, pyruvic acid is reduced to lactic acid by lactate dehydrogenase.
4. So the answer is lactic acid.
