Answer 1

question 3

Pepsin, which is secreted by the cells that line the stomach, dismantles the protein chains into smaller and smaller fragments.

In small intestine, the pancreas secretes digestive juice that contains more enzymes that further break down the protein fragments.The cells that line the small intestine release additional enzymes that finally break apart the smaller protein fragments into the individual amino acids.
