AIIMS 2019 Chemistry Hydrolases MCQ Question
Assertion : Hydrolases are the enzymes which catalyse the hydrolysis of ester, ether, peptide, glycosidic, or etc. bonds.
Reason : Lyases are the enzymes catalyzing the linking together of 2 compounds like joining of , or etc. bonds.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Hydrolases facilitate the process of hydrolysis, where large molecules are broken down into smaller units through the addition of water (H₂O), specifically utilizing its hydrogen and hydroxyl groups. This process is distinct from condensation, which refers to the formation of larger molecules by removing water, thus making option C incorrect. Hydration involves the addition of water without breaking bonds, while dehydration specifically refers to the removal of water to form bonds, both of which do not accurately describe the action of hydrolases in breaking down molecules.
