Audio Explanation:

(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.
