Answer:
e. the amino acids serine, histidine, and aspartate
Explanation:
Chymotrypsin is a digestive proteolytic enzyme secreted in the duodenum by the pancreas. It is a member of the serine proteases with active sites containing serine, histidine, and aspartate which it uses to cleave through hydrolysis (addition of a molecule of water) the c-terminus of aromatic amino acid tryptophan, tyrosine, and phenylalanine on peptide chains. Its hydrophobic pockets makes it suitable for aromatic amino acids.
