Detailed explanation-1: -[2] Most of the carbon dioxide diffusing through the capillaries and ultimately into the red blood cells combines with water via a chemical reaction catalyzed by the enzyme carbonic anhydrase catalyzes, forming carbonic acid.

Detailed explanation-2: -Carbon dioxide combines with water to form carbonic acid, a reaction accelerated by carbonic anhydrase. The carbonic acid then freely dissociates (Equation 1).

Detailed explanation-3: -Carbonic Anhydrase Reaction The enzyme carbonic anhydrase catalyzes the conversion of carbon dioxide and water into bicarbonate ions. The carbonic anhydrase formula demonstrates the conversion of carbon dioxide and water into carbonic acid, which is then converted to hydrogen ions and bicarbonate ions.
