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 ...

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 ...
