Detailed explanation-1: -An inhibitor may bind to an enzyme and block binding of the substrate, for example, by attaching to the active site. This is called competitive inhibition, because the inhibitor “competes” with the substrate for the enzyme. That is, only the inhibitor or the substrate can be bound at a given moment.
Detailed explanation-2: -A competitive inhibitor competes with the substrate for binding at the active site of the enzyme.
Detailed explanation-3: -Competitive enzyme inhibitors possess a similar shape to that of the substrate molecule and compete with the substrate for the active site of the enzyme. This prevents the formation of enzyme-substrate complexes.
Detailed explanation-4: -Competitive inhibitors work by camouflaging themselves as an enzyme’s natural substrate and binding to the enzyme’s active site, thereby blocking the natural substrate’s ability to bind to the enzyme’s active site. As binding affinity of a competitive inhibitor increases, enzyme activity decreases.
