This led to the discovery that to achieve the activity they were pursuing, the enzyme would need to first undergo a specific chemical modification. In fact, this modification should have been ...

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.

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 ...
