Pepsin, trypsin, and chymotrypsin are all proteolytic enzymes involved in breaking down proteins for digestion. Pepsin is produced in the stomach by chief cells and activated by stomach acid. Trypsin and chymotrypsin, on the other hand, are produced in the pancreas and delivered to the small intestine. These enzymes are stored in their inactive forms and are activated by trypsin in the duodenum. Additionally, the pancreas also produces other enzymes, such as elastase and carboxypeptidase, that aid in protein digestion. Overall, these enzymes play a vital role in breaking down proteins into smaller components for digestion and absorption in the small intestine.
