Q. No.Which one of the following statements is incorrect?
| 1. | A competitive inhibitor reacts reversibly with the enzyme to form an enzyme inhibitor. |
| 2. | In competitive inhibition, the inhibitor molecule is not chemically changed by the enzyme. |
| 3. | The competitive inhibitor does not affect the rate of breakdown of the enzyme-substrate complex. |
| 4. | The presence of the competitive inhibitor decreases the km of the enzyme for the substrate. |

Hints
Select the option which is not correct with respect to enzyme action:
| 1. | Substrate binds with the enzyme at its active site. |
| 2. | Addition of a lot of succinate does not reverse the inhibition of succinic dehydrogenase by malonate |
| 3. | A non-competitive inhibitor binds the enzyme at a site distinct from that which binds the substrate |
| 4. | Malonate is a competitive inhibitor of succinic dehydrogenase |
