Question

Choose incorrect statement from the following

• A. Ligases linking of C–O, C–S, C–N bonds
• B. Hydrolases catalysing C–C, C–halide, P–N bonds
• C. Isomerases catalysing transfer of a group between a pair of substrates
• D. Oxido reductase catalyse oxidation reduction reactions

Hint:

Match enzyme types with their specific functions — for example, ligases join bonds, hydrolases break bonds using water, and isomerases shift groups within molecules.

Answer 1

The Correct Option is B

Hydrolases do not typically catalyse reactions involving C–C, C–halide, or P–N bonds. They catalyse the hydrolysis of ester, glycosidic, peptide, and other bonds using water. The other statements correctly describe the functions of ligases, isomerases, and oxidoreductases.
