Question

Digestion of proteins is incomplete in the absence of enterokinase, because

• A. Pepsinogen is not converted into pepsin
• B. Chymotrypsinogen is not converted into chymotrypsin
• C. Trypsinogen is not converted into tryspin
• D. Prorennin is not converted into rennin

Answer 1

Answer: (C)

Trypsinogen is not converted into tryspin

Enterokinase is also called as enteropeptidase, an enzyme secreted by duodenum of the small intestine and involves in the digestion of food. It converts trypsinogen to active trypsin which digests protein into amino acids and completes the digestion of protein. But in the absence of enterokinase trypsinogen is not converted into the trypsin and thus the digestion of protein will be incomplete.
