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

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.

well when looking at this if you think about it   negativley and positivley   react with each other and when the first layer gets full they add layers it starts with 2 on the first layer and it constantly goes on until the official number is there
