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.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
