Tetanus is also commonly called lockjaw, because the infection primarily causes muscle contractions in the jaw and neck, but can eventually spread to other parts of the body. Without treatment, tetanus infection can be life-threatening.
Competitive inhibitors. The inhibitor (I) competes with the substrate (S) for the enzyme active site (also known as the S-binding site). Binding of either of these molecules in the active site is a mutually exclusive event. The substrate and inhibitor share a high degree of structural similarity.
Chemical factors like. inhibitors and cofactors also influence an enzymes activity. Inhibitors are. chemicals that selectively inhibit the action of specific enzymes. An inhibitor. can inhibit the function of a specific enzyme by competing the substrate for. the enzymes.
