Question

What causes the protein digestion there?

Answer 1

Enzymes and Amino Acids

Step-by-step explanation:

Mechanical digestion of protein begins in the mouth. There are two enzymes in our saliva called amylase and lipase. They mostly break down carbohydrates and fats. Then they are transferred to the stomach and at last go to small intestine. Once a protein source reaches our stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. In this way chemical digestion of protein begins in the stomach and ends in the small intestine.

Answer 2

The reason of the protein digestion process is that the dietary protein is reduced into a group of amino acids in the gastrointestinal tract. Proteins are globular molecules that are comprised of smaller molecules called amino acids.
