You are a physician, and see a patient who complains of abnormal fatigue during exercise. You find that the immediate problem is a buildup of carbon dioxide in the tissues. What is the most likely cause?
A) abnormally shaped platelets
B) abnormal carbonic anhydrase
C) not enough hemoglobin

Question

Quizplus · Accepted Answer

Abnormal carbonic anhydrase would affect the ability of the body to properly convert carbon dioxide into bicarbonate ion, leading to a buildup of carbon dioxide in the tissues during exercise. Abnormally shaped platelets and not enough hemoglobin would not directly affect carbon dioxide levels, and while abnormal hemoglobin may impact oxygen delivery to tissues, it would not cause a specific buildup of carbon dioxide during exercise.
