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

Correct answer: 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 Vmax remains same.
