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.
Enzymes are proteins that catalyze biochemical reactions. Each enzyme has a specific function, and one enzyme acts on one type of substrate -- the material that binds to the enzymeâs active site. The shape of the enzyme must match the substrateâs shape for the reaction to occur.ach enzyme has a specific function, and one enzyme acts on one type of substrate -- the material that binds to the enzymeâs active site.
