Question

3 multiple choice 1 point when the body has limited oxygen supply, like when sick or when exercising, the body produces ______ that makes muscles sore. ascorbic acid citric acid lactic acid antacid

Explanation:

Under limited oxygen (anaerobic conditions, e.g., intense exercise or illness), muscles produce lactic acid via anaerobic glycolysis, which accumulates and causes muscle soreness. Ascorbic acid is vitamin C, citric acid is in the Krebs cycle (aerobic), and antacid neutralizes stomach acid—none relate to muscle soreness from low oxygen.

Answer:

C. Lactic Acid
