What are different classes of enzymes? Explain any two with the type of reaction they catalyse.

Following are the different classes of enzymes:

1. Oxidoreductase

2. Transferase

3. Hydrolase

4. Lysases

5. Isomerase

6. ligases

a) Oxidoreductase:

These are the enzymes which help in simultaneous oxidation and reduction of two substrates.

b) Hydrolases:

These enzymes facilitate the hydrolysis of a molecule.
