Consider the given two statements:
| Assertion (A): | The effect of competitive inhibition can be overcome by increasing the substrate of the enzyme. |
| Reason (R): | The presence of a competitive inhibitor can decrease the rate of enzyme-catalyzed reaction by blocking the substrate from binding to the enzyme. |
