Vedclass · Answer

(A) The reaction $CO_2 + H_2O \rightleftharpoons H_2CO_3 \rightleftharpoons HCO_3^- + H^+$ occurs in the red blood cells $(RBCs)$.
This reaction is catalyzed by the enzyme Carbonic anhydrase.
Carbonic anhydrase is a zinc-containing enzyme that facilitates the hydration of $CO_2$ to form carbonic acid $(H_2CO_3)$ and its subsequent dissociation into bicarbonate $(HCO_3^-)$ and hydrogen ions $(H^+)$.
Both steps of this reversible reaction are catalyzed by the same enzyme,Carbonic anhydrase.
Therefore,both $P$ and $Q$ represent Carbonic anhydrase.

What are $P$ and $Q$ in the given reaction?
$CO _2+ H _2 O \underset{Q}{\stackrel{P}{\rightleftharpoons}} H _2 CO _3 \underset{Q}{\stackrel{P}{\rightleftharpoons}} HCO _3^{-}+ H ^{+}$
