An enzyme acts as a Catalyst because it speeds up the rate or ease at which a chemical reaction occurs.

Enzyme catalysis is the increment in the charge of a chemical effect by the existing site of a protein. The protein catalyst (enzyme) may be a member of a multi-subunit network, and/or may transiently or enduringly correlate with a Cofactor (e.g. adenosine triphosphate).

A catalyst is an agent or mixture that is affixed to a method to make a chemical effect occur more immediately. The catalyst can enhance the response flow of the vapour and can strive in the subsequent responses.
