What physicians need to know about restrictive covenants. Roy W. BreitenbachThe mention of restrictive covenants provokes an almost visceral reaction among most physicians. But keep in mind these covenants are, for the most part, enforceable.
An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. Since blocking an enzyme's activity can kill a pathogen or correct a metabolic imbalance, many drugs are enzyme inhibitors. medicinal enzyme inhibitor is often judged by its specificity (its lack of binding to other proteins) and its potency (its dissociation constant, which indicates the concentration needed to inhibit the enzyme). A high specificity and potency ensure that a drug will have few side effects and thus low toxicity.
If the temperature is too far below or too high above this range, the enzyme stops working. Enzymes work fastest when they are at the optimum temperature, but as the temperature gets lower the enzymeâs activity begins to decrease. Enzyme activity can be stopped by adding a molecule that binds to and blocks the enzyme. Lowering the temperature increases the effectiveness of some of these inhibitor molecules. Each enzyme has a special part called an active site, which is like a mouth. Reversible competitive inhibitors are molecules that fit into the mouth of the enzyme and jam it so that the enzyme cannot bite anything else.
