Question

The picture represents a protein in the stomach being broken down into individual amino acids. Which is mixed with proteins to break them into amino acids? villi enzymes saliva fat

Answer 1

Answer: read explanation

Explanation: Enzymes are mixed with proteins to break them down into amino acids. Pepsin is the main enzyme in the stomach that breaks down proteins into smaller peptide fragments. Further digestion into individual amino acids occurs in the small intestine with the help of enzymes from the pancreas and intestinal wall. Saliva and fat are not directly involved in protein breakdown. Villi in the small intestine help absorb amino acids into the bloodstream.
