Digestion summary

What goes where?

How does chemical digestion happen ?

Enzymes Enzymes are chemicals which break the larger molecules down into smaller molecules. They work like scissors!

Starch Amylase StarchSmall sugars

Why does digestion need 3 different enzymes?

Amylase - cuts the carbohydrate Starch into smaller sugar molecules. There are 3 types of enzymes we have to know about: Protease - cuts proteins down into amino acids. Lipase - cuts fats down into the smaller fatty acids and glycerol.

How does temperature affect enzymes?
