If, due to a certain condition, the parietal cells of the gut epithelium become partially non-functional, what would be the least likely consequence?
Sudden elevation in stomach pH
Decreased effectiveness of Steapsin
Adequate hydrolysis of proteins by Pepsin into Proteoses and Peptones
Impaired efficiency of pancreatic enzymes, particularly Trypsin and Lipase
Option 3 is the correct answer because when the parietal cells of the gut epithelium become partially non-functional, there is a reduction in the production of hydrochloric acid, which is necessary for the activation of pepsin. Pepsin is responsible for the hydrolysis of proteins into proteoses and peptones. Therefore, it is unlikely that there would be adequate hydrolysis of proteins in the absence of sufficient hydrochloric acid. The other options represent potential consequences of parietal cell dysfunction. Hence, the correct answer is option 3.
