3 combining with the product as soon as it is formed
4 lowering the activation energy of the reaction
Explanation:
(d) Activation energy is the energy required to overcome energy barrier of the reactants and make them reactive to start a chemical reaction. Enzymes lower the requirement of activation energy.

Select the option which is not correct with respect to enzyme action:
1 Substrate binds with enzyme at its active site.
2 Addition of 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.
Explanation:
(b) Inhibitions of succinic dehydrogenase by malonate is an example of competitive inhibition. Thus it is a reversible reaction. On increasing the substrate (succinate) concentration the effect of inhibitor is removed and ${{V}_{\text{max }\!\!~\!\!\text{ }}}$ remains same.
