Question

Assertion :Hydrolases are the enzymes which catalyse the hydrolysis of ester, ether, peptide, glycosidic, C-C or P-N etc. bonds. Reason: Lyases are the enzymes catalysing the linking together of 2 compounds like joining of C-O, C-N, P - O etc. bonds.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is C Assertion is correct but Reason is incorrect

There are various types of enzyme depending on their action. Hydrolases catalyse the hydrolysis of ester, ether, peptide, glycosidic, $C-C,C-halide,P-N$ bonds etc. which are formed by dehydration and condensation. Hydrolases break up large molecules into smaller ones with the help of hydrogen and hydroxyl groups of water molecules. The phenomenon is called hydrolysis. Lyases are the'enzymes which cause cleavage, removal of groups without hydrolysis, addition of groups to double bonds or removal of a group producing double bond, e.g histidine decarboxylase break histidine to histamine and $C{O}_2$.

So, the correct answer is 'Assertion is correct but Reason is incorrect'.
