start Our teeth break down food into small pieces when we chew.
This is because the food is too large to be absorbed!
For the food to be broken down special chemicals called Enzymes are needed
Are special proteins that break down large molecules into small ones.
They have a specific shape for the specific molecule and fit like a key in a lock
Protease enxymes break down proteins into amino acids.
Carboyhdrase enzymes break down carboyhydrates into sugar.
Lipase enzymes break down fats in fatty acids and glycerol.
If the shape changes the enzyme will no longer work!
