Solution

The correct option is B Conversion of trypsinogen into trypsin
The pancreatic proteolytic enzymes are secreted in inactive zymogen forms- trypsinogen, chymotrypsinogen and procarboxypeptidase. The enterokinase is the enzyme, which activates trypsinogen by converting it to trypsin. The chymotrypsinogen and procarboxypeptidase are activated by trypsin. Enterokinase is secreted by the duodenal mucosa.
