Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The enzyme class Lyase catalyses the removal of groups from substrates leaving double bonds. Reason (R): Hydrolases are enzymes that catalyse the hydrolysis of ester, ether, peptide, glycosidic, C-C, C-halide or P-N bonds. In the light of the above statements, choose the most appropriate answer fro
Options
- ABoth Assertion (A) and Reason (R) are correct and Reason (R) is the correct explanation of Assertion (A).
- BBoth Assertion (A) and Reason (R) are correct but Reason (R) is not the correct explanation of Assertion (A).
- CAssertion (A) is correct but Reason (R) is incorrect.
- DAssertion (A) is incorrect but Reason (R) is correct.
Correct answer
B. Both Assertion (A) and Reason (R) are correct but Reason (R) is not the correct explanation of Assertion (A).
Step-by-step solution
Assertion (A) is correct. According to the standard enzyme classification, Lyases are enzymes that catalyse the removal of groups from substrates by mechanisms other than hydrolysis, leaving double bonds. Reason (R) is also correct. Hydrolases are enzymes that catalyse the hydrolysis (cleavage via the addition of water) of ester, ether, peptide, glycosidic, C-C, C-halide, or P-N bonds. While both statements are factually correct definitions of their respective enzyme classes, Reason (R) does not explain Assertion (
