Question

Quizplus · Accepted Answer

Digestion of proteins begins in the stomach with the help of the enzyme pepsin, which breaks down proteins into smaller peptides. In the mouth and esophagus, there is no significant breakdown of proteins. The small intestine is where most of the breakdown of peptides into individual amino acids occurs. The large intestine is mainly responsible for absorption of water and electrolytes, and does not play a significant role in protein digestion.
