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.
What else can I help you with?
Did pepsin act in absence of HCL?
Pepsin is inactive in the absence of HCl because the acidic environment is necessary to convert pepsinogen into its active form, pepsin. HCl is needed to denature proteins and activate pepsin through a process called autocatalysis.
Why is HCl used to start the pepsin reaction?
To denature the protein. Pepsin can work pnly if the secondary structure of the protein is broken up.
Pepsin lost it function in alkaline pH?
Pepsin is an enzyme that functions optimally in acidic pH environments, such as the stomach. In alkaline pH conditions, pepsin can become denatured or inactivated, leading to a loss of its ability to break down proteins effectively. This is why pepsin is most active in the acidic environment of the stomach, where it helps in digesting proteins.
What is chemical found in the stomach needed to activate pepsinogen to pepsin?
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.
Is pepsin a peptidase?
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
Does pepsin affect pH?
Pepsin doesn't affect the pH but it is active in an acidic environment.
What organ is associated with pepsin?
The stomach (it digests proteins).
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.
How is pepsinogen activated in the stomach to become the active enzyme pepsin?
Pepsinogen is activated in the stomach by the acidic environment, which triggers a change in its structure to become the active enzyme pepsin.
Which organ secrets enzymes that are active at a low pH?
The stomach secretes protease enzymes that work best at a pH of around 2.
Why it is so that pepsin enzyme will not act if its active site is occupied by carbohydrate molecules?
The carbohydrate molecule should not get fitted into the pepsin enzyme.
Why would you predict the pepsin would not digest starch?
Because Pepsin is the active form of a protein manufactured in the stomach.
Did pepsin act in absence of HCL?
Pepsin is inactive in the absence of HCl because the acidic environment is necessary to convert pepsinogen into its active form, pepsin. HCl is needed to denature proteins and activate pepsin through a process called autocatalysis.
Why can pepsin not be produced in its active form?
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.
In which Organ of the digestive system does pepsin works?
Breaks down the proteins into peptide chains
What will happen if body just makes fully active form of enzymes?
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.
Explain the effect of pH on pepsin in terms of the active site of the enzyme?
nothing
