What else can I help you with?
Does pepsin affect pH?
Pepsin doesn't affect the pH but it is active in an acidic environment.
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.
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.
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.
In which organ is pepsin active?
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.
Explain the effect of pH on pepsin in terms of the active site of the enzyme?
nothing
Does hydrochloric acid produced in the stomach destroy pepsin?
No quite the opposite the low pH allows the autocleavage of pepsins zymogen pepsinogen into the active form pepsin.
Would pepsin work in your mouth?
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
