Carbonic anhydrase

Vedclass · Answer

(B) Zinc $(Zn^{2+})$ acts as a cofactor for many enzymes. Specifically, $Zn^{2+}$ is a crucial cofactor for the enzyme $Carbonic 	ext{ } anhydrase$. This enzyme catalyzes the reversible reaction of $CO_2$ hydration to form bicarbonate $(HCO_3^-)$ and protons $(H^+)$, which is essential for $CO_2$ transport in the blood. Therefore, the correct option is $B$.
