Question
What two substances are produced in the lining of the stomach?
Solution
The two substances produced in the lining of the stomach are hydrochloric acid and pepsin.
-
Hydrochloric Acid: This is a strong acid produced by the parietal cells in the stomach lining. It has several functions such as killing bacteria, activating pepsinogen into pepsin, and creating the right environment for enzymes to break down food.
-
Pepsin: This is an enzyme, also produced by the stomach lining, specifically by the chief cells. Pepsin plays a crucial role in the digestion of proteins by breaking them down into smaller peptides, which can then be absorbed in the small intestine.
