During intense exercise, when muscle cells cannot get enough oxygen fast enough, which fermentation product tends to build up in the muscle?
Correct Answer
Lactic acid
Explanation
When oxygen supply can't keep pace with demand during intense exercise, muscle cells rely more heavily on anaerobic fermentation, producing lactic acid as a byproduct.
