AIIMS 2019 Zoology Hydrolases MCQ Question
Enzymes are of various types depending on their action. Hydrolases catalyses the hydrolysis of ester, ether, peptide, glycosidic, C⁻C, C⁻halide, P⁻N bonds etc. They 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. This phenomenon is called
hydrolysis
hydration
condensation
dehydration
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.
