Question
Biology Question on Biochemistry
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
Lyases
Explanation
Solution
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.
