Solution

The correct option is C Enterokinase
Pancreatic juice is composed of various digestive enzymes like trypsinogen, chymotrypsinogen, elastase, carboxypeptidase, pancreatic lipase, nucleases and amylase. These enzymes help in further breakdown of carbohydrates, proteins and fats. Trypsinogen is a precursor form of trypsin. Trypsin is involved in breakdown of proteins. It cleaves the peptide bond of basic amino acids. The inactivated form trypsinogen is activated by enteropeptidase. It is also called as enterokinase. Enterokinase is produced by the duodenum and is found in the intestinal mucosa. It converts trypsinogen to trypsin.
Thus, the correct answer is option B.
