Issues for clarication included the practice of precision testing in which multiple bone density determinations are performed on one patient the use of quantitative computed tomographic CT densitometry and radiation dose to patients and operators Th C483 Spring 2013. Questions. 1. Which . statement is false about allosteric regulation? . A) It is usually the mode of regulation for the last step in reaction pathways since this step produces the final product. . Lecture 3. Objective. To understand . Specificity of enzymes. Specificity means:. Ability of an enzyme to . catalyse. a specific reaction and NO others. The active site. The . active site, . is. . C483 Spring 2013. Questions. 1. Enzymes . that join two substrates and require energy of a nucleoside triphosphate (such as ATP) to do so are called. A. ) . isomerases. .. B. ) . lyases. .. C. ) ligases.. Inhibition. C483 Spring 2013. Questions. 1. . An inhibitor binds to a site other than the active site of the enzyme. Which statement below correlates with this observation? . A. ) It must be a competitive inhibitor. . Inhibition is a term used to describe the inability of a product being formed due to the presence of another substance (the inhibitor). Enzyme inhibition . can be competitive or noncompetitive. Competitive inhibition is caused when an inhibitor “competes” with the substrate in binding with the enzyme. Pratt & . Cornely. . Ch. 7.
