Question

One of the constituents of the pancreatic juice, which is released into the duodenum of a man is

• A. Trypsin
• B. Chymotrypsin
• C. Trypsinogen
• D. Both B and C

Answer 1

The correct option is D Both B and C

Trypsinogen is an important protein splitting proenzyme present in pancreatic juice. Chymotrypsinogen and procarboxypeptidase are the other protein splitting proenzymes present in pancreatic juice. The trypsinogen is activated by the enzyme enterokinase. The active trypsin in turn activates chymotrypsinogen to chymotrypsin and procarboxypeptidase to carboxypeptidase.
