Pepsin is an enzyme found in the stomach.
It breaks proteins down into peptides.
Pepsinogen:
* is an inactive enzyme, so it doesn't digest the cells in the lining of the stomach. * is converted to pepsin by acid in the stomach * is secreted by cells in the lining of the stomach by zymogen (or chief) cells.
Pepsin is an enzyme that breaks down proteins in the stomach. It is secreted as pepsinogen by the chief cells of the gastric glands. Then, once pepsinogen encounters an acidic environment, it changes shape into its active form, pepsin.
Pepsin is active in the stomach. It is an enzyme produced by the stomach to help break down proteins into smaller peptides.
glands in the lining epithelium of the canal itself
Pepsin is found in the stomach. The enzyme digests protein.
Hydrochloric acid (HCl) is the chemical found in the stomach that is needed to activate pepsinogen to its active form, pepsin. HCl creates an acidic environment in the stomach that enables pepsinogen to undergo a conformational change and become pepsin, which is essential for protein digestion.
No. Pepsin is an enzyme that breaks down protein to peptides. Peptidase is another enzyme that breaks down peptides to amino acid. http://www.answers.com/topic/pepsin http://www.answers.com/topic/peptidase
Pepsin is stable at low pH because its optimal activity occurs in an acidic environment, specifically in the stomach where the pH is around 1.5-2. Additionally, pepsin has a unique structure that allows it to withstand the acidic conditions and maintain its functional properties.
no,pepsin does not acts in the absence of hydrochloric acid
Protein digestion requires the presence of both pepsin and HCl because pepsin needs an acidic environment to be able to "work" or do its job. Pepsin needs an environment with a pH around 2, which is roughly the pH of HCl. Therefore, HCl aids pepsin in protien digestions by creating an optimal environment for pepsin to work and digest proteins.
Pepsin doesn't affect the pH but it is active in an acidic environment.
The stomach (it digests proteins).
Pepsin is the active form of the enzyme found in the stomach that helps in the breakdown of proteins, while pepsinogen is the inactive precursor form of pepsin that is secreted by the stomach and is activated by acidic conditions to form pepsin.
Pepsin degrades proteins so if it was active it would immediately begin digesting all the proteins in the cell. Therefore it is produced from a precursor known as a zymogen or proenzyme. Pepsin's proenzyme form is pepsinogen which is transformed to the activated pepsin protein.
The carbohydrate molecule should not get fitted into the pepsin enzyme.
Because Pepsin is the active form of a protein manufactured in the stomach.
That is a proteolytic enzyme. Name of the enzyme is pepsin. It is secreted as inactive pepsinogen, which become active when it comes in contact with the hydrochloric acid, in the stomach.
Breaks down the proteins into peptide chains
Consider the stomach. The inactive form of the digestive enzyme pepsin is called pepsinogin. ( spelling may be wrong ) It takes the release of hydrochloric acid in the stomach to activate this pre-enzyme into pepsin, the active form. You would be digesting your own stomach tissue if pepsin was always active.
nothing
No quite the opposite the low pH allows the autocleavage of pepsins zymogen pepsinogen into the active form pepsin.
No. Pepsin is the active form of a protein manufactured in the stomach called pepsinogen. In order to become active, it has to come into contact with HCl (hydrochloric acid). HCl isn't present in your mouth (I hope!), so pepsinogen, even if it WERE in your mouth, could never become active there.No, the pepsin enzyme is located in the stomach, the enzymes amylase and lipase are found in saliva in the mouth
