Final answer:
Enzymes produced in the pancreas are activated in the small intestine through the actions of a specific enzyme called enteropeptidase. This enzyme triggers the activation of other pancreatic enzymes and allows them to carry out their functions in the small intestine.
Step-by-step explanation:
The pancreas produces protein-digesting enzymes in their inactive forms. These enzymes are activated in the duodenum of the small intestine. The intestinal brush border enzyme enteropeptidase stimulates the activation of trypsin from trypsinogen of the pancreas, which then changes other pancreatic enzymes into their active forms.
