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.
In non-competitive inhibition, the inhibitor binds to the enzyme at a site different than the active site. Binding to this site, however, changes the overall shape of the enzyme, slowing the processing of substrate into product once it is bound to the enzyme.n competitive inhibition, the inhibitor resembles the chemical structure of the true substrate, and it competes with the substrate for binding to the active site. The inhibitor is only able to bind the free enzyme, and cannot bind the substrate-enzyme complex.
