PhysiologyThe activation of pancreatic enzymes involves a cascade. Enterokinase, an enzyme present in the brush border of the small intestinal epithelial cells, first cleaves trypsinogen into active trypsin. Trypsin then cleaves chymotrypsinogen into chymotrypsin. This process continues with chymotrypsin activating proelastase and procarboxypeptidase A and B into their respective active forms, which are essential for the complete breakdown of proteins in the small intestine.
