Question

Enzymes that catalyse the removal of groups from substrates by mechanisms other than hydrolysis leaving double bonds, are known as :

• A. Transferases
• B. Oxidoreductases
• C. Dehydrogenases
• D. Lyases

Answer 1

The Correct Option is D

Lyases are a class of enzymes that catalyze the cleavage of C-C, C-O, C-N, and other bonds by means other than hydrolysis or oxidation. They often form double bonds or rings in the process.
The other options are incorrect:

• Transferases: Catalyze the transfer of a functional group from one molecule to another.
• Oxidoreductases: Catalyze oxidation-reduction reactions.
• Dehydrogenases: A subclass of oxidoreductases that specifically catalyze the removal of hydrogen atoms.
