2.10 Effect of pH on the rate of reaction

1. On the y axis we are measuring the rate of reaction and on the x axis we are changing the pH.
2. If it is more alkilin or more acidic the rate gradually decreases.
3. When we complete the graph, we see that the graph is symmetrical.
4. Acidic and alkilin conditions change the shape of the active site which slows the reaction.
5. The optimum pH is not necessarily 7. For instance, the enzyme in the stomach, pepsin has an optimum pH of pH3.

6. An enzyme that has an optimum of pH 7, is salivary amylase
