Question

what is the function of enterokinase?
a it activates trypsin.
b it activates pepsin.
c it neutralizes the ph of chyme.

Explanation:

Enterokinase (also called enteropeptidase) is an enzyme in the small intestine. Its key role is converting inactive trypsinogen (from the pancreas) into active trypsin, which initiates protein digestion. Pepsin is activated by stomach acid, not enterokinase. Bicarbonate neutralizes chyme pH, not enterokinase.

Answer:

A. It activates trypsin.
