What enzyme breaks down proteins and what are the products?
Protease breaks down proteins into amino acids.
2 of 12
What enzyme breaks down Starch and what are the products?
Amalayse breaks down starch into maltose and simple sugars.
3 of 12
What enzyme breaks down Lipids and what are the products?
Lipase breaks down lipids into fatty acids and glycerol.

What does the small intestine do?
Breaks down starch, proteins, lipids and uses villi to absorb them into the blood stream.
5 of 12
What does the large intestine do?
Absorbs excess water and mineral ions from the food.
6 of 12
What is the function of the stomach?
Produces protease (called pepsin) and HCl to maintain the correct pH for enzymes to work and to kill bacteria (pH 2).
