Question:

Chymotrypsinogen and pro-carboxypeptidase of pancreatic juice are activated by

Options:

1. Enterokinase
2. Exopeptidase
3. Trypsin
4. Enteropeptidase

Solution:

Chymotrypsinogen and pro-carboxypeptidase are inactive precursors of chymotrypsin and carboxypeptidase, respectively. These precursors are activated by an enzyme called trypsin, which is also secreted by the pancreas in an inactive form called trypsinogen. When chyme from the stomach enters the duodenum, it triggers the release of a hormone called secretin, which stimulates the release of pancreatic juice rich in bicarbonate ions. The bicarbonate ions neutralize the acidic chyme and create a slightly alkaline environment in the duodenum, which is necessary for the activation of pancreatic enzymes. Enterokinase, also known as enteropeptidase, is an enzyme produced by the intestinal mucosa that activates trypsinogen to trypsin. Once trypsin is activated, it can then activate chymotrypsinogen and pro-carboxypeptidase to chymotrypsin and carboxypeptidase, respectively.
