Vedclass · Answer

(A) During intense physical activity like running,the demand for energy in muscle cells increases rapidly.When the oxygen supply is insufficient to meet this demand,muscle cells perform anaerobic respiration.In this process,pyruvate is converted into lactic acid instead of entering the aerobic pathway.The accumulation of lactic acid in the muscle fibers leads to muscle fatigue and cramps.
