NEET Zoology Biomolecules Questions Solved

Select the option which is not correct with respect to enzyme action:
(a) Substrate binds with enzyme at its active site
(b) Addition of lot of succinate does not reverse the inhibition of succinic dehydrogenase by malonate
(c) A non-competitive inhibitor binds the enzyme at a site distinct from that which binds the substrate
(d) Malonate is a competitive inhibitor of succinic dehydrogenase

Correction: If substrate succinate concentration is increased, it will remove malonate from its active site and thus succinate reverses the inhibition of dehydrogenase.

This is an example of competitive reverse inhibition.
