EAMCETEAMCET 2010

Solution:

Ptyalin is present in mammalian saliva for the initial stages of starch digestion. Pepsin is an enzyme in the stomach chat begins the digestion of proteins by splitting them into smaller pieces. Carboxypeptidase is a protepse enzyme that hydrolyses the peptide bond of an ammo acid residue at the carboxy-terminal (c- terminal) end. Dipeptidase is secreted by enterocytes into the small intestine.
