Explain Functions of the Pancreas - Digestive Action
Trypsinogen and chymotrypsinogen are the inactive proteolytic enzymes of the pancreatic juice. When they come in contact with enterokinase of the intestinal juice, they are converted to trypsin and chymotrypsin, respectively as illustrated herewith.
Trypsin and chymotrypsin, you know are the enzymes that act on partially digested proteins. This means that they convert peptones (formed in the stomach) into peptides and polypeptides. Other enzymes called ribonuclease and deoxyribonuclease, act on two types of nucleic acids (ribonucleic acid and deoxyribonucleic acid).
