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.
An uncompetitive inhibitor cannot bind to the free enzyme, only to the enzyme-substrate complex; hence, these types of inhibitors are most effective at high substrate concentration. In the presence of the inhibitor, the enzyme-substrate complex is inactive.nzymes /ËÉnzaÉªmz/ are macromolecular biological catalysts. Enzymes accelerate, or catalyze, chemical reactions. The molecules at the beginning of the process are called substrates and the enzyme converts these into different molecules, called products.
