What are enzymes inhibitors?

Explanation

The chemicals that can shuts off enzymes activity are called enzymes inhibitors . They are of three types . Inhibits the activity of the enzymes are called Competitive inhibitors .
E.g inhibition of Succinic Dehydrogenase by Malonate which closely resemble the substrate Succinate .
B. Non - competitive inhibitors : The inhibitors which have no structual similarity with the substrate and bind to an enzymes is changed are called Non - competitive inhibitors .
C. Feedback inhibitors : The ne product of chain of enzymes catalysed reactions inhibits the enzymes of the first reaction as part of homeostatic control of metabolism is called feedback inhibitors . E.g : During respiration ,accumulation of Glucose - 6 phosphate occurs , inhibits the Hexokinase.
