Enzyme Structure
Catalysts increase the rate of reaction. Enzymes are biological catalysts.
Enzymes are protein molecules made up of long chains of amino acids. Chains are folded to form active sites. This is where the substrate of the reaction binds with the enzyme.

The minimum amount of energy particles need to collide with in order to react is called the activation energy. Reaction more likely to happen if you can make it:

more likely
