pH is a measure of how acidic or alkaline a solution is. The diagram below shows what happens to an enzyme when denaturation occurs. Each enzyme has an optimum pH but it also has a working range ...

This is shown in the graph below. In the graph above, as the pH increases so does the rate of enzyme activity. An optimum activity is reached at the enzyme’s optimum pH, pH 8 in this example.

Acid phosphatase hydrolyses phosphate ester bonds under an optimum pH of 4.8 and an optimum temperature of 37 °C ... 5.5 mM). 5. Now you have to determine enzyme activities in all the original ...
