Question

In which part(s) of the alimentary canal does the complete digestion of egg white take place?

• A. Stomach only
• B. Stomach and small intestine
• C. Large intestine only
• D. Mouth only

Answer 1

The correct option is B Stomach and small intestine

Digestion of proteins starts in the stomach by the action of the enzyme pepsin present in the gastric juice. Pepsin breaks down protein into smaller peptides. Further digestion of these peptides into amino acids occurs in the small intestine. Here pancreatic enzymes like trypsin and intestinal enzymes like peptidases further break down undigested proteins into amino acids.
