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.nzymes can change the equilibrium point of reactions, but they cannot speed up reactions because they cannot change the net energy output. b. Enzymes can greatly speed up reactions, but they cannot change the net energy output because they cannot change the activation energy.
