JEE Main levelSingle correct optionDifficulty 2 of 3el151
A drug binds to an enzyme at a site other than the active site, and this binding changes the shape of the active site so that the substrate can no longer bind. This type of inhibition is called
Aallosteric inhibition
Bcompetitive inhibition at the active site
Creceptor agonism
Dcatalytic activation
Answer: A
Binding at a site away from the active site that distorts the active site is allosteric inhibition. A competitive inhibitor would sit in the active site itself.
