WebTherefore, competitive inhibition can be overcome by increasing the substrate concentration, taking care of the inhibition by the substrate. In competitive inhibition, K m increases, but V max is unchanged (Kuddus, 2024; Roskoski, 2007). Figure 34.3.

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.
