Correct answer
A. trypsinogen into trypsin
Step-by-step solution
The pancreatic juice contains inactive enzymes- trypsinogen, chymtorysinogen, procarboxypetidases, amylases, lipases and nucleases. Trypsinogen is activated by an enzyme, enterokinase, secreted by the intestinal mucosa into active trypsin, which in turn activates the other enzymes in the pancreatic juice.
