Expert Solution
Step 1

Trypsin is an enzyme that is used to cleave the peptide bond. The enzyme specifically cleaves the peptide carboxyl end of lysine/arginine. The enzyme is synthesized and secreted by the pancreatic cells in its zymogen form. 

The zymogen, trypsinogen, is cleaved by the enzyme enterokinase to form trypsin. The catalytic activity of the trypsin is due to the catalytic triad present in its active site.
