Question

Quizplus · Accepted Answer

Chymotrypsinogen is the inactive precursor of chymotrypsin, an enzyme involved in protein digestion. Once activated, chymotrypsinogen is converted into chymotrypsin, which can hydrolyze peptide bonds in proteins. Chymotrypsinogen is not activated by enterokinase, which activates trypsinogen, another precursor enzyme. Chymotrypsinogen is not secreted by the endocrine pancreas, but rather by the acinar cells of the exocrine pancreas. Chymotrypsinogen does not hydrolyze starches and glycogen, which are carbohydrates.
