Inorganic catalysts

Enzymes

1. These are simple mineral ions or small molecules.

2. These can catalyse diverse reaction.

3. They are not regulated by any regulator molecules.

4. They are less sensitive to temperature and pH.

5. They have low molecular weight.

1. These are proteins with complex three dimensional structures.

2. They catalyse only specific reactions of a single or only a few substrates.

3. They can be regulated by specific molecules which can change conformation and hence activity.

4. They are more sensitive to change in temperature and pH.

5. They have high molecular weight.
