Quizplus · Accepted Answer

Pancreatic proteases are endopeptidases, which means they break peptide bonds within the protein chain rather than at the terminal amino acids. This action results in peptide fragments rather than complete digestion into amino acids. Other enzymes, such as exopeptidases from the pancreas and the intestinal lining, are needed to further break down these fragments into amino acids.
