Question

During intense exercise, when hydrogen oxidation does not keep pace with its production, the pyruvate temporarily binds with which molecule to form lactate?

• A. Oxygen
• B. NADH
• C. Hydrogen
• D. FADH

Hint:

Lactic acid buildup can cause muscle soreness and fatigue. Proper recovery strategies, including stretching and rest, are important to clear lactic acid and prevent discomfort.

Answer 1

The Correct Option is C

During intense exercise, when oxygen supply is limited, the body switches to anaerobic respiration. In this process, pyruvate accepts a hydrogen ion (H+) to form lactate. This process is known as lactic acid fermentation.
