Put the protein digestion steps in order of their occurrence during the digestive process.

Protein digestion is a process of reducing the dietary protein into a pool of amino acids in the gastrointestinal tracts. These amino acids are then absorbed and transported to cells where they will mix and form variety of proteins the body needs. However, the process of digestion takes place in the mouth and ends in the small intestine with the help of enzymes and digestive juices.

Steps

· Mouth: chewing of protein rich food which increase the surface area of the food particles and aid the process of digestion.

· Stomach: the acid in the stomach denature and unfold the protein rich foods in other for digestive enzymes to act on the protein. This digestive enzyme digests the protein into smaller molecules called peptides.

· Small intestine: In the small intestine, more protein- digesting enzymes  that originate from pancreas and cells lining in the stomach work on the peptides and break them down into smaller peptides and sniped off the amino acid one by one.
