Webcompetitive inhibition chemical substance has a shape that fits the active site of an enzyme and competes with the substrate, effectively inhibiting the enzyme. resistance factors encode antibiotic resistance antibiotic A chemical that kills bacteria or slows their growth without harming body cells. prophylaxis prevention of disease
WebThe binding of substrate (S) at the active site prevents the binding of inhibition (I) at a separate site and vice versa They're kind of like 2,3BPG with hemoglobin. Uncompetitive inhibition The inhibition (I) binds only to the enzyme-substrate (ES) complex preventing the conversion of substrate (S) to product WebSubstances that reduce an enzyme's activity by reversibly combining with it in a way that influences the binding of the substrate and/or its turnover number.
