E) citric acid

Question

Quizplus · Accepted Answer

During short-term, but vigorous, activity, the body's demand for ATP increases. In the absence of oxygen, the body undergoes anaerobic respiration, which produces ATP through glycolysis. The end product of glycolysis is pyruvic acid, which is converted to lactic acid in the absence of oxygen. Lactic acid accumulation can cause muscle fatigue and soreness. Therefore, the compound that accumulates as a result of anaerobic respiration for short-term, but vigorous, activity is lactic acid (choice B).
