The following reaction depicts the activity of a particular class of enzymes :

Identify the enzyme class 'E' from the following options :

A Transferases
B Isomerases
C Lyases
D Ligases

Verified Solution

Answer & Solution

Correct Answer

(A) Transferases

Step-by-step Solution

Detailed explanation

(A) Lyases
he given reaction shows the removal of groups X and Y from the substrate, resulting in the formation of a double bond \((C=C)\) between the carbon atoms.
Enzymes that catalyze the removal of groups from substrates by mechanisms other than hydrolysis, leaving double bonds, are classified as lyases.
Therefore, the enzyme class 'E' is Lyases.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
