Are all enzymes a catalyst ? and what relation exist between catalyst and enzyme ?​

Enzymes and catalysts both affect the rate of a reaction. In fact, all known enzymes are catalysts, but not all catalysts are enzymes. The difference between catalysts and enzymes is that enzymes are largely organic in nature and are bio-catalysts, while non-enzymatic catalysts can be inorganic compounds

Explanation:

All known enzymes are catalysts, but not all catalysts are enzymes

Catalysts are substances that increase or decrease the rate of a chemical reaction but remain unchanged. Enzymes are proteins that increase rate of chemical reactions converting substrate into product.
