You are a biochemist and just discovered a chemical that can inhibitthe activity of the human xanthine oxidase. When analyzing its mode of inhibition, you foundthat the enzyme inhibitor complex requires 450 J.mol-1 to dissociate and that it displayskinetics somehow similar to noncompetitive inhibition.
