Detailed Solution

Statement I is correct. Both the formation and dissociation of carbonic acid are facilitated by the enzyme carbonic anhydrase. This enzyme catalyses the reversible conversion of carbon dioxide and water into carbonic acid, as well as the subsequent dissociation of carbonic acid into bicarbonate ions (HCO₃^-) and hydrogen ions (H⁺). This process is essential for the transportation of carbon dioxide from tissues to the lungs for exhalation and helps maintain the pH balance of the blood.
${HCO}_{3}^{-} + H^{+} \overset{Carbonic anhydrase}{\to} H_{2} {CO}_{3} \overset{Carbonic anhydrase}{\to} {CO}_{2} + H_{2} O$

Statement II is also correct. RBCs contain a very high concentration carbonic anhydrase and minute quantities of the same is present in the plasma too.
