View solution & NCERT explanation
Correct answer: C — Lyases
Lyases catalyse the breaking of various chemical bonds by means other than hydrolysis and oxidation, often forming a new double bond or ring structure. Hydrolases break bonds via hydrolysis, ligases join molecules, and transferases transfer functional groups. Hence, lyases are correctly matched to non-hydrolytic group removal.
