Question

Enzymes that catalyse endergonic synthesis, coupled with exergonic hydrolysis of ATP are

• A. Ligases
• B. Isomerases
• C. Lyases
• D. Transferases

Answer 1

The correct option is A Ligases

There are six major classes of enzymes, as follows:

(1) Oxidoreductases - Catalyze oxidationreduction reactions.

(2) Transferases - Catalyze the transfer of a functional group from a donor molecule to an acceptor molecule.

(3) Hydrolases - Catalyze hydrolysis reactions.

(4) Isomerases - Catalyze conversion of a molecule from one isomeric form to another.

(5) Ligases - Ligases or synthetases are enzymes that catalyse endergonic synthesis, coupled with the exergonic hydrolysis of ATP

(6) Lyases - Catalyze certain reactions in which double bonds form or break.
