Q. Refer the statements I.Carbonic anhydrase is present in the erythrocytes. II.In erythrocytes, the carbon dioxide combines with water and is transported.
A) Statement I is correct and is responsible for statement II
B) Statement I is not correct but statement II is correct
C) Both statements I and II are wrong
D) Statement I is correct but not involved in statement II
Explanation
Carbonic anhydrase is an enzyme present in the red blood corpuscles (erythrocytes) of blood. It has a role during ${CO}_{2}$ transportation in plasma. Most of ${CO}_{2}$ produced by tissues diffuses passively into the blood plasma and reacts with water forming carbonic acid. This reaction occurs very rapidly inside RBCs because of the presence of enzyme carbonic anhydrase.
