WebFigure 8.7. 1: Metabolic pathways are a series of reactions catalyzed by multiple enzymes. Feedback inhibition, where the end product of the pathway inhibits an upstream … WebNegative allosteric modulation (also known as allosteric inhibition) occurs when the binding of one ligand decreases the affinity for substrate at other active sites. For example, when 2,3-BPG binds to an allosteric site on hemoglobin, the affinity for oxygen of all subunits decreases. This is when a regulator is absent from the binding site.
WebApr 10, 2024 · A main competitive inhibition example can be seen in the case of methotrexate. This inhibitor resembles the appearance of the folate substrate that is present in the enzyme dihydrofolate reductase or DHFR.
