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
