Lactic acid fermentation in muscle cells converts pyruvate to
A.lactate, oxidizing NADH
B.ethanol and CO₂
C.acetyl-CoA
D.glucose
Explanation
Core Concept
Lactate dehydrogenase reduces pyruvate to lactate using NADH, regenerating NAD⁺. This sustains brief high-intensity effort.
Correct Answer
Alactate, oxidizing NADH
