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.
An enzyme lowers the activation energy of a chemical reaction. c. Most enzymes are proteins. d. An enzyme is consumed during the reaction it catalyzes. e. An enzyme is very specific in terms of which substrate it binds to.. Enzymes react with their substrate (form chemical bonds), forming an enzyme-substrate complex, which irreversibly alters the enzyme. c. Enzymes increase the rate of a reaction by raising the activation energy for reactions. d. Enzymes speed up the rate of the reaction without changing the DG for the reaction.
