Which of the following pancreatic proteases is classified as an 'exopeptidase', meaning it cleaves individual amino acids from the ends of peptide chains?
Show answer and explanation
Correct answer: Carboxypeptidase B
Trypsin, chymotrypsin, and elastase are endopeptidases that break internal peptide bonds. Carboxypeptidases A and B are exopeptidases that specifically remove amino acids one by one from the carboxyl (C-terminal) end of the peptide.
