Cells in the wall of stomach produce pepsinogen. which plays a role in protein digestion. Why don't these cells digest themselves?

Because they are coated, along with the stomach, in a thick mucus made by glans in the stomach, when the mucus is penetrated by the acid, that is when ulcers are caused

Protein digestion in the stomach results primarily from secretions released by what?
Protein digestion in the stomach results primarily from secretions released by the gastric glands. The enzyme that is secreted is called pepsinogen.
Churns food and begins protein digestion?
When pepsinogen is mixed with hydrochloric acid, it makes pepsin. Pepsin is the enzyme that begins the digestion of proteins in stomach.
What does the pre digestion of protein produce?
Amylases
What is the functiom of pepsinogen?
Pepsinogen is the precursor for Pepsin, an enzyme for the degradation of protein.
What does the pre-digestion of protein produce?
amino acids
Pepsinogen is the precursor to the gastric enzyme for protein digestion and is secreted by the parietal cells?
it is secreted by stomach glands as an inactive proenzyme, pepsinogen, which is converted to pepsin by the cleavage of acid-labile linkages in the acidic (low pH) environment of the stomach.
Secretions from the stomach promote the digestion of what?
If you mean what is stomach acid in chemical terms? HCL.
Where the digestion of the proteins begins?
Chemical digestion of proteins begin in the stomach.In the stomach.The digestion of proteins begin at the stomach.The stomach. There are recesses in the wall of the stomach called pits. These pits produces pepsinogen and HCl as well are protective mucous. Pepsinogen is the zymogen (inactive form) of pepsin the enxyme which breaks down protein. It is cleaved form the zymogen form into the active form in very low pH situations, this is why HCl is secreted here.MouthChemical digestion of protein starts in the stomach.It would begin in the stomach. It would occur by the action of an enzyme called pepsin.In the stomach
What type of foods are digested by the small intestine?
Proteins are digested in your stomach. Pepsinogen is secreted by the chief cells. Pepsinogen is converted to pepsin by hydrochloric acid. This pepsin brakes the peptide bond of proteins to form polypeptides.

What is the most important enzyme in gastric juice?
Pepsin is the most important enzyme in gastric juice. It begins the digestion of nearly all types of dietary protein into polypeptides. (Originates from the inactive form pepsinogen)
What is the approximate pH of gastric juice that will ensure proper digestion?
stomach acid works at an optimum level of 2.4. the reason of this is because the pepsinogen in the stomach cavity will not be properly activated into pepsin unless the level of H+ concentration is substantially high. pepsin is needed for protein digestion.
