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.
Substrate in active site. Enzymes are proteins, and their function is determined. by their complex structure. The reaction takes place in a. small part of the enzyme called the active site, while the. rest of the protein acts as scaffolding.
