What prevents pepsin from destroying the cell walls in the stomach?

Pepsin is secreted as pepsinogen. Pepsinogen cannot eat the walls of the stomach. Now, pepsin is formed when pepsinogen binds to the hydrochloric acid (HCl) in the stomach. Once they are binded pepsin is formed. The second reason on why the stomach doesn't eat it's self is because of the alkaline mucus that suround the walls of the stomach.

Why does the absorption of nutrients occur in the small intestine and not the stomach?
the walls of the stomach is alkaline and the food contain in the stomach is acidic.. it will not accept the nutrients to enter inside the stomach walls. the small intestine having villa in the walls and it ll absorb the nutrients in the food.
The walls of this organ are thrown into folds called rugae?

What protects your stomach walls from acid?
A lining of mucus is what protects ur stomach from hydrochloric acid
What protects the stomach wall from the potential damage by this chemical products?
The mucous is the substance that protects the stomach walls from digestion. The mucous cells are found throughout the stomach lining and secrete mucus which protects the stomach from its own digestive secretions.
How do the wall of the stomach different from the wall of the esophagus?
The stomach has to digest the food. The wall of the esophagus has to pass the food to stomach. So the walls of both are designed by nature like that.
What does the walls of the stomach contain?
The walls of the stomach contain a thick layer of mucus. The stomach itself is filled with pepsin and Hydrochloric acid in order to digest food. The thick layer of mucus prevents these acids from digesting the wall of your stomach. Occasionally this mucus recedes and some of the acid can get in. When this occurs, it causes a Peptic Ulcer.
How are gastric juice and pepsin related?
gastric juice is secreted by the walls of the stomach and it contains pepsin and dilute hydrochloric acid. Pepsin helps in breaking down proteins into pep-tones or peptides during the process of digestion in the stomach.
What does the wall of the contain?
The walls of the stomach contain a thick layer of mucus. The stomach itself is filled with pepsin and Hydrochloric acid in order to digest food. The thick layer of mucus prevents these acids from digesting the wall of your stomach. Occasionally this mucus recedes and some of the acid can get in. When this occurs, it causes a Peptic Ulcer.
Why are the walls of houses often filled with fiberglass?
I think it has something to do with maintaing the temperature in the home. Ventilation. Also, it prevents humidity from destroying the interior of walls.
Is your stomach lined with mucus?
Yes, your stomach is lined with mucus. The chemicals the stomach secretes (i.e., pepsin) are designed to digest protein. But your stomach walls are also made of protein! The mucus coats the lining of your stomach so the chemicals do not destroy the lining.
Why isn't the stomach affected by the gastric juice?
there is a lining of mucus around the entire stomach that prevents the gastric acid (gastric juice) from penetrating the stomach walls
What would be happen if HCL were not secreted in stomach?
Hydrochloric acid is secreted by the glands present on the stomach walls. It dissolves bits of food and creates an acidic medium. The acidic medium allows pepsinogen to be converted into pepsin. Pepsin plays an important role in the digestion of proteins. Therefore, if HCl were not secreted in the stomach, then pepsin would not be activated. This would affect protein digestion. A pH of about 1.8 is necessary for proteins to be digested. This pH is achieved by HCl.
What class of food is partially digested in stomach?
Glands on the stomach walls secrete gastric juice containing Pepsin (a type of protease), which breaks down proteins into smaller molecules called peptides.
Why does walls of the stomach secrete hydrochloric acids?
Hydrochloric acid is secreted from the stomach because the enzyme pepsin, which breaks down proteins in the stomach, works best in acidic conditions. The acid also helps to kill any bacteria in the food. The hydrochloric acid is actually secreted from the pits in the stomach wall called gastric pits.
Why is the stomach not digested by gastric juice?
The cells lining your stomach secrete a mucous that protects them from being damaged by caustic digestive enzymes. A stomach ulcer, for example, is the result when those cells fail to maintain that mucous and the cells are left exposed to digestive enzymes.
What are gastric juices and what do that contain?
Gastric juices are produced in the gastric pits and secreted into the StomachThey contain pepsin(a type of protease) an enzyme that breaks down proteins, acid which makes the pepsin break down food faster and mucus that coats the walls of your stomach to stop the enzymes breaking them down as well.Read more: Discuss:What_is_the_function_of_the_gastric_juice_in_the_stomach
Why digestive acid cannot digest stomach?
The inner lining of the stomach is coated in a thick layer of protective mucus that prevents powerful digestive acids and enzymes from damaging the organ. The stomach walls themselves are thick membranes that are similarly protective against corrosion.
