Answer
The proenzyme versions of most proteases in the small intestine are cut into active versions by the enzyme enteropeptidase.
Solution
a
Enteropeptidase: This enzyme is responsible for the activation of trypsinogen to trypsin
b
Trypsin: Once activated, trypsin can then activate other protease proenzymes into their active forms
Key Concept
Enteropeptidase is the key enzyme that initiates the activation of protease proenzymes in the small intestine.
Explanation
Enteropeptidase cleaves specific peptide bonds in trypsinogen, converting it into its active form, trypsin, which in turn activates other proteases.
