Solution
Enzymes are classified into six groups based on their mode of action.
| S. No. | Enzymes | Mode of action | General scheme of reaction | Example |
| 1. | Oxidoreductase | Oxidation and reduction (redox) reactions | Ared+Box Aox + B red | Dehydrogenase |
| 2. | Transferase | Transfer a group of atoms from one molecule to another | A-B+C A C B | Transaminase, phosphotransferase phosphotransferase |
| 3. | Hydrolases | Hydrolysis of the substrate by addition of water molecule | A B + H2O A H + B OH | Digestive enzymes |
| 4. | Isomerase | Control the conversion of one isomer to another by transferring a group of atoms from one molecule to another | A B C -- A C B | Isomerase |
| 5. | Lyase | Break chemical bond without the addition of water | A B A B | Decarboxylase |
| 6 | Ligase | Formation of new chemical bonds using ATP as a source of energy | A + B + ATP A - B + ADP + Pi | DNA ligase |
