What is common among amylase, rennin and trypsin ?
(a) These all are proteins
(b) These all are proteolytic enzymes
(c) These are produced in stomach
(d) These ast as a pH lower than 7
(a) Amylase, rennin and trypsin-all the three are proteinaceous enzymes. However, only rennin and
trypsin act on proteins. Amylases breakdown starches and glycogens to sugars. Trypsin is produced by pancreas. It together with chymotrypsin and carboxypeptidase completes the digestion of proteins in the small intestine.
Rennin is secreted by stomach of young mammals. It converts soluble caseinogen to the insoluble
protein casein which coagulates and therefore, takes some to leave the stomach.
