Question

If for some reason the parietal cells of the gut epithelium become partially nonfunctional, what is likely to happen:

• A. Pancreatic enzymes, specially trypsin and lipase will not work efficiently.
• B. Proteins will not be adequately hydrolysed by pepsin to proteoses and peptones.
• C. pH of stomach will fall abruptly.
• D. Steapsin will not be effective.

Answer 1

Answer: (B)

Parietal cells secrete HCl which act as an activator for enzymes pepsinogen. This enzyme helps in the digestion of protein. Hence, if for some reason the parietal cells of the gut epithelium become partially non-functional, proteins will not be adequately hydrolyzed by pepsin into proteases and peptones.

Hence, the correct answer is (B)
