Question

Match List-I with List-II: 

List-I		List-II
(A)	Ligases	(II)	Formation of bonds with cleavage of ATP
(B)	Oxidoreductases	(I)	Transfer of electrons or hydrogen atoms
(C)	Lyases	(IV)	Addition to double bonds in a molecule
(D)	Hydrolases	(III)	Addition of a water molecule to break a chemical bond

• A. \(A\text{-I},\ B\text{-III},\ C\text{-II},\ D\text{-IV}\)
• B. \(A\text{-IV},\ B\text{-II},\ C\text{-I},\ D\text{-III}\)
• C. \(A\text{-III},\ B\text{-IV},\ C\text{-I},\ D\text{-II}\)
• D. \(A\text{-II},\ B\text{-I},\ C\text{-IV},\ D\text{-III}\)

Hint:

Remember enzyme classes:
• Oxidoreductases \(\rightarrow\) Redox reactions
• Hydrolases \(\rightarrow\) Hydrolysis reactions
• Lyases \(\rightarrow\) Add/remove groups forming double bonds
• Ligases \(\rightarrow\) Bond formation using ATP

Answer 1

The Correct Option is D

Concept: Enzymes are classified into different groups based on the type of biochemical reactions they catalyze. Major enzyme classes include:
• Oxidoreductases
• Transferases
• Hydrolases
• Lyases
• Isomerases
• Ligases

Step 1: Matching Ligases. Ligases catalyze: \[ \text{Formation of chemical bonds} \] usually coupled with: \[ \text{ATP cleavage} \] Thus: \[ A \rightarrow II \]

Step 2: Matching Oxidoreductases. Oxidoreductases catalyze: \[ \text{Transfer of electrons or hydrogen atoms} \] during oxidation-reduction reactions. Thus: \[ B \rightarrow I \]

Step 3: Matching Lyases. Lyases catalyze: \[ \text{Addition to double bonds} \] or removal of groups to form double bonds without hydrolysis. Thus: \[ C \rightarrow IV \]

Step 4: Matching Hydrolases. Hydrolases catalyze bond cleavage by: \[ \text{Addition of water} \] Thus: \[ D \rightarrow III \]

Step 5: Determining the correct combination. Therefore: \[ \boxed{ A\text{-II},\ B\text{-I},\ C\text{-IV},\ D\text{-III} } \] Hence, the correct answer is: \[ \boxed{(D)\ A\text{-II},\ B\text{-I},\ C\text{-IV},\ D\text{-III}} \]
