The correct option is
A Proteolytic enzyme
- Chymotrypsin is a proteolytic digestive enzyme component of pancreatic juice acting in the duodenum, where it performs proteolysis, the breakdown of proteins and polypeptides.
- Digestion of protein is completed in the small intestine by the pancreatic enzymes trypsin, chymotrypsin, and carboxypeptidase. Hence, Chymotrypsin is a proteolytic enzyme.
So, the correct answer is 'proteolytic enzyme'.
