Question: From NCERT NEET 2020
The intrinsic factor that helps in the absorption of vitamin is secreted by-
1. Goblet cells
2. Hepatic cells
3. Oxyntic cells
4. Chief cells
Answer ▽
3
Answer (4) Oxyntic cells
Sol. The correct answer is option (4) because parietal or oxyntic cells secrete HCl and intrinsic factor (factor essential for absorption of vitamin B12) .
Peptic or chief cells secrete proenzyme pepsinogen. Goblet cells secrete mucus. Hepatic cells secrete bile

Question: From NCERT NEET 2008
What will happen if the secretion of parietal cells of gastric glands is blocked with an
inhibitor?
1. Gastric juice will be deficient in chymosin
2. Gastric juice will be deficient in pepsinogen
3. In the absence of HCl secretion, inactive pepsinogen is not converted into the active
enzyme pepsin
4. Enterokinase will not be released from the duodenal mucosa and so trypsinogcn is not
converted to trypsin
