Question

Which enzyme converts trypsinogen into trypsin?

Hint:

Enterokinase activation of trypsinogen is essential for initiating the cascade of digestive enzymes necessary for protein digestion in the small intestine.

Answer 1

1. Trypsinogen, the inactive zymogen form of trypsin, is essential for protein digestion.
2. Enterokinase (enteropeptidase), produced by duodenal cells, specifically cleaves trypsinogen to activate it into trypsin.

Conclusion: Enterokinase is the enzyme that converts trypsinogen to its active form, trypsin.
