Vedclass · Answer

(C) Assertion $(A)$: About $70\%$ of $CO_2$ is carried in the plasma as bicarbonate ions $(HCO_3^-)$. This statement is true.Reason $(R)$: The enzyme carbonic anhydrase is present in high concentrations in red blood cells and facilitates the reaction: $CO_2 + H_2O \rightleftharpoons H_2CO_3 \rightleftharpoons H^+ + HCO_3^-$. This enzyme catalyzes the formation of bicarbonate ions. This statement is also true.Since both statements are scientifically accurate and the reason explains the mechanism behind the transport, the correct option is $C$.

$A = CO_2$ is carried in the plasma mainly as $HCO_3^-$ ions.
$R =$ Carbonic anhydrase catalyzes the formation of $HCO_3^-$ ions.
