Question

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

Answer 1

Correct Answer - C
(C) Malonate is a competitive inhibitor of succinic dehydrogenase.
Substrate binds with enzyme at its active site.
Addition of lot of succinate reverse the inhibition of succine ddhyrogenase by malonate.
A non-competitive inhibitor bind the enzymes at a site distinct from that which binds the substrate.
