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.
1 They are usually specific to only one reaction. 2  The part of the Enzyme that acts a Catalyst is called the Active Site. 3  The rest of the Enzyme is much larger and is involved in maintaining the specific shape of of the Enzyme. 4  When a reaction involving an Enzyme occurs, a Substrate is turned into a Product. Enzymes work by lowering the Activation Energy of a reaction. 2  The Activation Energy of a reaction is lowered by putting stress on the bonds within a molecule, or by holding molecules close together. 3  This increases the likelihood of a reaction, and so lowers the energy required to begin it.
