Vedclass · Answer

(D) The correct answer is $D$. $1$. Parietal cells (also known as oxyntic cells) are responsible for the secretion of hydrochloric acid $(HCl)$ and the intrinsic factor. $2$. The $HCl$ secreted by these cells lowers the $pH$ of the stomach to an acidic range $(1.8 - 3.5)$,which is essential for the activation of the proenzyme pepsinogen into its active form,pepsin. $3$. Pepsin is a proteolytic enzyme that hydrolyzes proteins into smaller peptides like proteoses and peptones. $4$. If the parietal cells become non-functional,the secretion of $HCl$ will decrease or stop,leading to a failure in the conversion of pepsinogen to pepsin. $5$. Consequently,the digestion of proteins in the stomach will be severely impaired.

If for some reason the parietal cells of the gut epithelium become partially non-functional,what is likely to happen?
