Select the option which is not correct with respect to enzyme actionA. Malonate is a competitive inhibitor of succinic dehydrogenaseB. Substrate binds with enzyme at its ac- tive siteC. Addition of lot of succinate does not re- verse the inhibition of succinic dehydro- genase by malonateD. A non-competitive inhibitor binds the enzyme at a site distinct from that which binds the substrate |
| Answer» Inhibition of succinate dehydrogenase by malonate is an example of competitive inhibition , where malonate occupies the active site fo the enzyme and blocks it .Howere , this kind of inhibition is reversible and increase in substrate concentration will reverse the inhibition .In non-competitive inhibition the inhibitor binds to the enzyme at a site different form its substrate (i,e the active site ). | |
