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. |
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 |
A competitive inhibitor of succinic dehydrogenase is:
1. | malonate | 2. | oxaloacetate |
3. | α-ketoglutarate | 4. | malate |
