Question

Explain the digestion and absorption of proteins in human intestine

Answer 1

Protein digestion begins with the action of an enzyme called pepsin. ... Pepsin acts on proteinmolecules by breaking the peptide bonds that hold the molecules together. Digestion of protein is completed in the small intestine by the pancreatic enzymes trypsin, chymotrypsin, and carboxypeptidase.

Answer 2

Digestion :-

Here it is mixed with gastric acid until it passes into the duodenum where it is mixed with a number of enzymes produced by the pancreas. Saliva also contains a catalytic enzyme called amylase which starts to act on food in the mouth. ... Most of the digestion of food takes place in the small intestine.

Absorption of proteins :-

The pancreas secretes digestive juice that contains more enzymes that further break down the protein fragments. The two major pancreatic enzymes that digest proteins are chymotrypsin and trypsin... The muscle contractions of the small intestine mix and propel the digested proteins to the absorption sites.
