Pepsin, a common enzyme found in the stomach, is most active at ph values between 0.5 and 2.5. it works slowly between ph values of 2.6 and 3.4. beyond a ph of about 3.5, it becomes completely inactive. why does this happen?

Pepsin is an enzyme which is very specific to temperature and pH for its working.

Explanation:

The pepsin is an enzyme which is found in the stomach and works best at pH which ranges between 0.5-2.5. This the pH that matches the pH of the stomach so that it works he best.

In case the pH is below this or above this the enzyme gets denatured as it is proteinous in nature. The denatured enzymes is inactive in nature and will not work on the protein.

Hence, the enzymes are very specific to the temperature and pH for its working.

b.have there own function.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
