Define Enzyme and Active site

Enzymes are biological catalysts that are formed from globular proteins.

Active site is the molecule surface space where the substrate binds and catalysis occurs.

Extra points:

- Enzymes are NOT used up in a reaction

- Enzymes are substrate specific. This means the active site on the enzyme is fairly specific to what substrate it catalyses.
