WebAn inhibitor is similar in shape to the usual substrate for the enzyme thus, it competes with the substrate for the active site. Malonate is a competitive inhibitor. It inhibits the enzyme succinate dehydrogenase. Malonate binds to the active site of this enzyme without reacting and competes with succinate which is the usual substrate of the enzyme. WebThe reaction is affected by malonate ions which have a very similar shape to succinate ions. The similar shape allows the malonate ions to bind to the active site of the enzyme and …
