Protein digestion occurs in stomach only because it is safe for the body, as stomach has mucous secretions which prevents self digestion of stomach muscles by PEPSIN (enzyme for protein digestion) :)

What are the enzymes produced in the stomach?
The main enzyme in the Stomach is Pepsin which is used to digest protein. Only protein digestion occurs in the stomach and almostt no absorption, (only a little alcohol). This protein is not secreted as its active form (ie not as pepsin) but as the Zymogen (the inactive precursor to proteins) Pepsinogen which cleaves in a low pH to form the active enzyme.
Where is Pepsin (protease) located in the body?
Pepsin is found in the stomach of a human being. It turns food proteins into peptides and is considered a digestive protease.
Which enzyme works best in neutral conditions?
These are secreted by the stomach:pepsiogen precursor for pepsin (an enzyme)intrinsic factor (so that B12 can be absorbed)gastrin (a hormone)ghrelin (a hormone)Only pepsin fits your question as pepsiogen needs HCl to convert into pepsin.Pepsin.
Enzyme found in gastric juices?
the enzyme found in gastric juice is Pepsinogenand it only works in an acidic environment (hydrochloric acid is in the stomach)then when that enzyme gets mixed with the hydrochloric acid it creates pepsin and pepsin breaks down proteins into amino acid chainsthere are also other enzymes like:HClReninPepsinogenGelatinaseGastric AmylaseGastric Lipase
Changing the pH in an enzyme will?
Changing the pH in the environment that an enzyme works in can change how active it will be. Most will be active in a narrow range. Pepsin, a stomach enzyme, will only work at very acid pHs and will become inactive at higher pH than 2.
Why H. pylori is not destroyed by stomach acid?
Granted pepsin could kill a cell by hydrolyzing crucial proteins, it doesn't specifically destroy cells. It is a protease, a protein-digesting enzyme. There are two reasons why pepsin does not, under normal conditions, turn around and start digesting the cells of the host. Pepsin is only present in the stomach, where it is compartmentalized from the rest of the body. The mucous membrane protects the lining of the stomach so the stomach is not degraded by the enzymes or the strong hydrochloric acid. Secondly, pepsin is only active as an enzyme in very acidic environments like that of the stomach. Once the chyme of the stomach is dumped into the duodenum of the small intestine, the pH increases dramatically and the pepsin is denatured, no longer active to digest protein.
Where is pepsin produced?
pepsin (which breaks down protein) is produced in the stomach unlike the enzymes amylase (which breaks down carbohydrates) and lipase (which breaks down lipids or fats) which are produced in the pancreas.
What is the enzyme called in your stomach?
There are many digestive juices in your stomach, the main ones are hydrochloric acid (HCl) and peptin. Peptin is an enzyme that digests proteins and HCl is an acid that dissolves most everything else. The stomach can only digest proteins. Carbohydrates and lipids are digested in the small intestine, where most digestion takes place.
How might very low pH affect an enzyme's hydrogen bonds?
A very low pH can break the hydrogen bonds in an enzyme which causes the shape of the enzyme to change shape making the enzyme unable to do it's job. This is called "denaturation" However some enzymes such as pepsin only work in a low pH (pepsin works best in a pH of about 3) so it does depend on the enzyme.
What is the difference between pepsin and pepsinogen?
Pepsin is a powerful protein digesting enzyme which is far too dangerous in its active form so it is released in an inactive pepsinogen form by the cell and activated only in the digestive tract where it is required to be active.
Which stomach enzyme is low in optimum pH?
Because the chemical that works in the stomach- pepsin (a chemical that breaks down proteins) only works in acidic conditions, which is low pH. Hope that helps
Do all enzymes work best at neutral pH?
No, the optimum pH for an enzyme depends on the environment in which it normally works. Your stomach is an acidic environment which contains an enzyme called pepsin. This not only works better in acid environments but actually denatures (that is, totally stops working) if the pH rises above 5.0.
