What accumulates in the muscles after continuous strenuous physical exercise as a result of temporary anaerobic respiration that causes muscular fatigue? (1) ATP (2) Lactic acid (3) Ethyl alcohol (4) Carbon dioxide

Description : What accumulates in the muscles after continuous strenuous physical exercise as a result of temporary anaerobic respiration that causes muscular fatigue? (1) ATP (2) Lactic acid (3) Ethyl alcohol (4) Carbon dioxide

Last Answer : (2) Lactic acid Explanation: Anaerobic reactions break down glucose into pyruvic acid, which then reacts to produce lactic acid. As muscle metabolism shifts from aerobic to anaerobic ATP production, ... begins to accumulate in muscles and to appear in the bloodstream. This leads to muscle fatigue.
