WebCOMPETITIVE INHIBITOR: When active/catalytic site of an enzyme is occupied by substance other than substrate of that enzyme, its activity is inhibited. Inhibitor must be structural analog of substrate. In such inhibition, both ES & EI (Enzyme-Inhibitor) complexes are formed. With the increase in conc. of inhibitor lowers the rate of …
Enzyme competitive inhibition example
Did you know?
In competitive inhibition of enzyme catalysis, binding of an inhibitor prevents binding of the target molecule of the enzyme, also known as the substrate. This is accomplished by blocking the binding site of the substrate – the active site – by some means. The Vmax indicates the maximum velocity of the reaction, while the Km is the amount of substrate needed to reach half of the Vmax. K… WebNon-competitive inhibitors. The inhibitory effects of heavy metals, and of cyanide on cytochrome oxidase and of arsenate on glyceraldehyde phosphate dehydrogenase, are examples of non-competitive inhibition. This type of inhibitor acts by combining with the enzyme in such a way that for some reason the active site is rendered inoperative.
