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.
â¢ Enzymes are proteins that act as catalysts. Catalysts increase the rate of a chemical reaction without being consume by the reaction. Enzymes are not altered during a reaction and therefore they can be reused again and again.â¢ An enzyme speeds up a reaction by lowing the reactionâs activation energy.ll reactions require some energy to get started (activation energy). Enzymes lower the activation energy they do not provide activation energy. All chemical reactions require activation energy (Ea). Without enzymes reaction in cells would be slow and take a very long time.â¢ Enzymes are specific for certain reactions.
