State the role of pancreatic juice …

Pancreatic juice contains a variety of inactive enzymes such as trypsinogen, chymotrypsinogen, and carboxypeptidases. These enzymes play an important role in the digestion of proteins. The enzyme enterokinase is secreted by the intestinal mucosa. It activates trypsinogen into trypsin. Trypsin then activates the other enzymes of pancreatic juice such as chymotrypsinogen and carboxypeptidase. Chymotrypsinogen is a milk-coagulating enzyme that converts proteins into peptides. Carboxypeptidase acts on the carboxyl end of the peptide chain and helps release the last amino acids. Hence, it helps in the digestion of proteins.

The pancreatic juice contains enzymes that complete the digestion of starch called pancreatic amylase. It also contains pancreatic enzymes that complete the digestion of protein called trypsin, chymotrypsin and carboxypeptidase.
