WebDue to this fact, it is less likely for the enzyme to de-nature. However, for pH level 7.4 and 6.0, I think that the enzyme will not affect the rate of reaction as the acid and alkali levels are too high and also too low, which will cause the active site to denature, not allowing the lock and key theory to take place. Apparatus: 1 ... WebFeb 19, 2024 · How does pH affect the rate of an enzyme? The closer the pH is to 7, the higher the reaction rate. As the pH distances from the optimum, however, the reaction rate decreases because the shape of the enzyme’s active site begins to deform, until it becomes denatured and the substrate can no longer fit the active site.
