Food is chewed into small pieces by the teeth

3

What happens to proteins in the stomach?

Gastric juices are secreted which contain hydrochloric acid, rennin and pepsin

4

It denatures proteins

5

What does rennin do to proteins in the stomach?

Caseinogen is broken down into casein

Pancreatic juice is secreted into the duodenum which contains trypsin

8

What does trypsin do to proteins?

Trypsin breaks down peptones into peptides
