The parietal cells or the oxyntic cells located in the stomach's gastric pits mainly secrete:-
1. HCI and Intrinsic factor
2. Pepsinogen and Gastric lipase
3. Pepsinogen and Pro-rennin
4. Gastrin and Mucus

Pepsin converts:

(1) Protein into amino acid

(2) Fat into fatty acid

(3) Peptones into amino acid

(4) Proteins into proteoses and peptones (peptides)

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

The pH of stomach is 1.6, then which enzyme will digest protein ?

(1) Trypsin

(2) Pepsin

(3) Amylase

(4) Erypsin

The initial step in the digestion of milk in infants is carried out by?

(1) Lipase

(2) Trypsin

(3) Rennin

(4) Pepsin

Which of the following gastric secretory cells is correctly matched with its secretion(s)?

1. Chief cells - gastrin

2. parietal cells -- hydrochloric acid and intrinsic factor

3. enteroendocrine cells -- mucus and hormones

4. mucous cells -- pepsinogen and mucus

Which of the following gastric secretions is correctly matched with its source?
(1) Pepsin-Chief cells

(2) Chymotrypsin-Parietal cells

(3) HCl-Goblet cells

(4) Mucus-Oxyntic cells

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

(1) The pancreatic enzymes and specially the trypsin and lipase will not work efficiently

(2) The pH of stomach will fall abruptly

(3) Steapsin be more effective

(4) Proteins will not be adequately hydrolysed by pepsin into proteoses and peptones

The food in stomach is called

(1) Bolus

(2) Chyme

(3) Chyle

(4) Food vacuole

HCl provides the pH which is about 

(1) 1.8

(2) 3.2 

(3) 5.0

(4) 6.8
