Question

Quizplus · Accepted Answer

Abnormal carbonic anhydrase can lead to a buildup of carbon dioxide in the tissues during exercise, resulting in fatigue. Carbonic anhydrase is an enzyme that catalyzes the conversion of carbon dioxide and water to bicarbonate and hydrogen ions in red blood cells. If this enzyme is not functioning properly, it can lead to a buildup of carbon dioxide in the tissues, causing fatigue.
