QuestionSBA
QuestionChoice
Parietal cells of the stomach secrete hydrochloric acid. This hydrochloric acid converts the pepsinogen secreted by the chief cells into pepsin, which breaks down the protein in food into amino acids and peptides.

c
Hydrochloric acid
QuestionChoice
There is no evidence to indicate sulphuric acid secretion by any cells in the stomach. Chief cells secrete pepsinogen, which reacts with hydrochloric acid to form pepsin, the endopeptidase which breaks down the protein in food into amino acids and peptides.

d
Sulphuric acid
QuestionChoice
This is close to being correct. The chief cells secrete pepsinogen, a proenzyme, that is converted to pepsin through a reaction with hydrochloric acid in the stomach. Pepsin is an endopeptidase involved in the initial digestion of proteins within food to amino acids and peptides.

b
Pepsin
QuestionChoice
Correct - pepsinogen is a proenzyme secreted by chief cells of the stomach. It reacts with hydrochloric acid to form pepsin, the endopeptidase involved in the initial digestion of proteins within food to amino acids and peptides.

a
Pepsinogen
QuestionChoice
There is no evidence to indicate magnesium sulphate secretion by any cells in the stomach. Chief cells secrete pepsinogen, which reacts with hydrochloric acid to form pepsin, the endopeptidase involved in the initial digestion of proteins within food to amino acids and peptides.

A 41 year old man is counselled on the use of proton pump inhibitors by an advanced nurse practitioner, after a recent diagnosis of gastro-oesophageal reflux disease. The nurse explains that the stomach contains chief cells that have a secretory function.

Which of the following compounds is secreted by chief cells of the stomach?
a
