Enzymes & Your Body

Enzymes are Catalyst Enzymes speed up chemical reactions.

Activation Energy Enzymes work by lowering the activation energy needed to start a chemical reaction.

Enzymes are Reusable Enzymes are reusable molecules found in living things.

Enzyme Form and Function Lock & key Model: The shape of an enzyme allows it to do a specific job much like a lock and key.

Induced Fit Model Enzymes can form to the shape of its substrate.

Denaturing Enzymes When an enzyme is denatured (unfolded) it is damaged. Denaturing changes the shape. Without the correct shape enzymes won’t function properly. HOW are enzymes denatured? Temperature pH

Enzyme Inhibitors Chemicals that prevent the enzyme from working. Inhibitors decrease the enzyme reaction rate.

Enzymes are used all over your body!
