Comparison between inorganic catalysts and enzymes

Inorganic catalysts	Enzymes
1.      They are mineral ions or small molecules	They are globular proteins
2.      They can promote diverse reaction	They can promote a specific reaction of a substrate
3.      They are not regulated by any regulator molecules	They are regulated by specific molecules
4.      They are less sensitive to temperature and pH	More sensitive to temperature and pH
5.      They are not synthesized in the living cells	They are synthesized by ribosomes in the living cells
