Question

If for some reason the parietal cells of the gut epithelium become particularly non-functional, what is likely to happen?
a. The pancreatic enzymes especially the trypsin and lipase will not work efficiently.
b. The Ph of the stomach will fall abruptly.
c. Steapsin will be more effective.
d. Proteins will not be adequately hydrolysed by pepsin into proteoses and peptones.

Answer 1

Hint: Parietal cells are available in organs inside the fundus and body of the stomach and are the biggest cells in these organs. They start from immature begetter cells in the organ isthmus and afterward relocate upward toward the pit locale and descending toward the base of the organ. Parietal cells, along with the other gastric epithelial cells, are sorted out into gastric organs, the useful units of the gastric corrosive secretory framework.

Complete answer:
The parietal cells or oxyntic cells are huge, adjusted cells situated upon the outside of gastric organs. These cells discharge $HCl$ (which changes over inert pepsinogen into dynamic pepsin) and Castle's Intrinsic Factor of CIF (which helps in the retention of cyanocobalamin).

Assuming by one way or another, parietal cells become incompletely non-utilitarian, the patient will experience the ill effects of achlorhydria (no $HCl$) or hypochlorhydria (less $HCl$). This will result in the non-enactment of the pepsinogen because of which the proteins won't be sufficiently hydrolyzed into proteases and peptones.

Hence, the correct answer is option (D).

Additional information:
- Trypsin is a protease like pepsin, the protein-processing chemical in the stomach. It will not function admirably because of the way that pepsin works in an acidic climate.
- Individuals with low stomach corrosive levels battle to process meat and other protein nourishments. It is therefore that you may feel drained, woozy, or queasy in the wake of eating a meal.
- Steapsin is the other name for the catalyst lipase. This is one of the stomach related catalysts which is liable for the absorption of fat.

Note: Pepsin denatures ingested protein and changes over it into amino acids. Without pepsin, our body would be unable to process proteins. Gastric boss cells emit pepsin as a latent zymogen called pepsinogen. Parietal cells emit $HCl$ which goes about as an activator for chemicals pepsinogen. This chemical aids in the assimilation of protein. Thus, if for some reason the parietal cells of the gut epithelium become incompletely non-functional, proteins will not be satisfactorily hydrolyzed by pepsin into proteases and peptones.
