Answer:
Enteropeptidase
Explanation:
Proteolytic enzymes or proteases are enzymes that breakdown molecules of proteins into shorter fragments, peptides or even into their basic units, amino acids.
Proteolytic enzymes in the small intestine are produced and secreted by the pancreas. They are secreted as inactive precursors or zymogens (trypsinogen, chymotrypsinogen, proelastase, and procarboxypeptidase). Zymogens are then transformed to their active form by an enzyme enterokinase or enteropeptidase which is secreted from the walls of the small intestine.
