What accumulates in the muscles after continuous strenuous physical exercise as a result of temporary anaerobic respiration that causes muscular fatigue ? ATP Lactic acid What accumulates in the muscles after continuous strenuous physical exercise as a result of temporary anaerobic respiration that causes muscular fatigue ? ATP Lactic acid A)Ethyl alcohol B)Carbon dioxide C)Ethyl alcohol D)Carbon dioxide
Option B) 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, lactic acid begins to accumulate in muscles and to appear in the bloodstream. This leads to muscle fatigue.
