Describe the role of CCK release and its effects on proteins
What will be an ideal response?
The arrival of acidic chyme in the duodenum triggers the release of CCK, which stimulates the production and release of inactive pancreatic proenzymes. Enteropeptidase, released from the duodenum, converts the pancreatic proenzyme trypsinogen into the proteolytic enzyme trypsin. Trypsin then converts other proenzymes to yield chymotrypsin, carboxypeptidase, and elastase. Each of these enzymes attacks peptide bonds that link specific amino acids while ignoring others. As a result, they break down proteins into a mixture of dipeptides, tripeptides, and amino acids.
