Enzymes

• Proteins• Act as catalysts to speed up chemical

reactions• Are specific – each enzyme can carry out

only one type of reaction.• Animation of Enzyme activity

Inhibitors

• Slow down chemical reactions.– Competitive inhibitors compete with

substrates for the active site– Allosteric inhibitors change the shape of the

active site so the substrate can’t attach to the enzyme
