Select the option which is not correct with respect to enzyme action:
1. | Substrate binds with 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. |
All the following are examples of competitive enzyme inhibition except:
1. | Sulfa drugs used as antibacterial agents |
2. | Ethyl alcohol used in methyl alcohol poisoning |
3. | Malonate inhibiting succinic dehydrogenase enzyme |
4. | Glucose 6 phosphate inhibiting hexokinase in brain |
