Question

Match the following.

\[ \begin{array}{|c|l|c|l|} \hline \text{List-I} & & \text{List-II} & \\ \hline A & \text{Dehydrogenases} & \text{I} & \text{Elimination of groups to form a double bond} \\ \hline B & \text{Transferases} & \text{II} & \mathrm{CO_2 + H_2O \rightarrow H_2CO_3} \\ \hline C & \text{Lyases} & \text{III} & \mathrm{S\text{-}G + S' \rightarrow S + S'\text{-}G} \\ \hline D & \text{Carbonic anhydrase} & \text{IV} & \text{Oxidation--reduction reaction} \\ \hline \end{array} \]

• A. A--III, B--II, C--I, D--IV
• B. A--IV, B--III, C--I, D--II
• C. A--IV, B--I, C--III, D--II
• D. A--II, B--III, C--I, D--IV

Hint:

Major enzyme classes: \[ \boxed{ \begin{aligned} &\text{Oxidoreductases} &&\rightarrow \text{Redox reactions} &\text{Transferases} &&\rightarrow \text{Transfer groups} &\text{Lyases} &&\rightarrow \text{Form/remove double bonds} &\text{Carbonic anhydrase} &&\rightarrow \mathrm{CO_2+H_2O\leftrightarrow H_2CO_3} \end{aligned} } \]
