WebExplanation: . Competitive inhibitors bind the active site of enzymes, and compete with the substrate for this binding site. Thus, the does not change since if enough substrate is added, regardless of the differential affinities between the substrate and inhibitor for the active site, the substrate will outcompete the inhibitor. However, increases upon the … 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…
