Question

Describe the digestion of protein in human alimentary canal? ​

Answer 1

Answer:

Protein digestion occurs in the stomach and duodenum in which 3 main enzymes, pepsin secreted by the stomach and trypsin and chymotrypsin secreted by the pancreas, break down food proteins into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids.

Answer 2

Proteins are very essential for the body. It provides energy and helps muscles and bones.

• Protein helps to make new cells and also repair the old ones.
• Digestion of protein starts the very first moment when we start chewing the food.
• Our saliva contains two enzymes amylase and lipase.
• When protein content reaches the stomach it breaks down into the amino acid chain.
• Hydrochloric acid and proteases enzymes break down the protein content.
• Then this small chain of amino acids moves to the small intestine.
• Enzymes released by the pancreas and a bicarbonate buffer reduce the acidity.
