Question

Quizplus · Accepted Answer

Chymotrypsinogen is the inactive precursor of chymotrypsin, which is involved in protein digestion. It is activated by trypsin, not enterokinase. It is secreted by the exocrine pancreas, not the endocrine pancreas. It does not hydrolyze starches and glycogen, as it is specific to protein digestion.
