leading to an increase in enzyme activity. This means the active site loses its important shape and can no longer form enzyme-substrate complexes, leading to a decrease in enzyme activity.

Because enzymes are not part of the product, they can be reused again and again. How efficient! Enzyme activity measures how fast an enzyme can change a substrate into a product. Changes in ...

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.
