NEET PG DENTAL EXAM

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. Carbonic acid almost immediately dissociates into a bicarbonate anion (HCO3-) and a proton.

Detailed explanation-2: -CO2 diffuses into the red blood cells and is converted to H+ and HCO3-by an enzyme called carbonic anhydrase.

Detailed explanation-3: -Carbon dioxide in your blood usually causes no problems. But if you have too much or too little of it, you may have a disease or a health emergency. Most of the carbon dioxide in your body is in the form of bicarbonate. Bicarbonate is used to keep the pH of your blood (acids and bases) in balance.

Detailed explanation-4: -The majority of carbon dioxide is transported as bicarbonate ions. This is because erythrocytes have a high activity of carbonic anhydrase, an enzyme that catalyzes the reaction between carbon dioxide and water.
