Vedclass · Answer

(D) In the process of human digestion,the inactive enzyme pepsinogen is secreted by the chief cells of the stomach.When pepsinogen comes in contact with hydrochloric acid $(HCl)$,it is converted into its active form,pepsin.Pepsin is responsible for the digestion of proteins into peptides.Other options are incorrect because: $1$. Trypsinogen is activated by enterokinase,not chymotrypsin.$2$. Procarboxypeptidase is activated by trypsin.$3$. Amylase is secreted in its active form (salivary amylase) or activated by other mechanisms,but 'proamylase' is not a standard term in this context.
