In what form is most carbon dioxide carried in blood, and why is it useful?
Answer and explanation
Correct answer: As bicarbonate because it can be carried easily in blood
The governing concept is transport of respiratory gases. Carbon dioxide produced by cellular respiration diffuses into the blood. Most of it reacts with water in red blood cells, with the help of carbonic anhydrase, and is converted into bicarbonate ions. These ions are soluble and can be transported efficiently in plasma to the lungs, where carbon dioxide is released and exhaled. Hence option A is correct; coal, starch and bile are unrelated substances.
