Question

One of the constituents of the pancreatic juice which is poured into the duodenum in humans is

• A. Trypsinogen
• B. Chymotrpsin
• C. Trypsin
• D. Enterokinase

Answer 1

The correct option is A Trypsinogen

Pancreatic juice is secreted by the pancreas. It contains proenzymes- trypsinogen, chymotrypsinogen and procarboxypeptidase and enzyme elastase. All these are concerned with digestion of proteins. Trypsinogen is the constituent which is poured into the duodenum in humans. With the help of enterokinase enzyme present in the intestinal juice, trypsinogen gets converted into trypsin which is its active form. Trypsin breaks protein molecules into large peptides.
