Km/Vmax4. 1/VmaxDr. Vanier’s daughter Lexy thinks that the snacking habit alone does not cause weight loss. She believes that one needs to combine no snacking with the elimination of carbohydrates in their meals. Please explain how Dr. Vanier may test this hypothesis by describing the research design. Specify the independent variable(s), dependent variable(s), and the name of the design. Finally, describe what she needs to find (i.e., what type of effect and what it looks like) in the experiment to support her hypothesis. ( name the IV(s); 1name the DV(s); name the design; then explain the effect that will support the hypothesis)What do you mean by relative biological effectiveness (RBE)?

- In an enzyme experiment, when the enzyme is added only to the substrate, the Vmax value is 0.828 and the Km value is 17.76. When the substrate and activator are added to this enzyme, the Vmax is 0.964 and the Km value is 10.6066. When substrate and inhibitor are added to the enzyme, the Vmax value is 0.550 and the Km value is 11.34. Estimate the effect of the substance added. Are these substances suitable activators/inhibitors for the laccase enzyme?Name the three basic classes of drug targets in medicinal chemistry and indicate, which are the most/least important as targets for biologics? I don't sure if I answer these questions correctly. Hope someone can give me confirmation and explain to me how enzymes will be affected by bioloigcs? My answer so far: The three common classes of drug targets are; receptors, nucleic acid, and enzymes. As a target for biologics, the least important will be a nucleic acid, and the most important will be receptor and second enzymes. Biologic drugs such as monoclonal antibodies will bind to the antigens, which are overexpressed receptor that need to be deactivated. In this case, the monoclonal antibodies will act as an antagonist and block the ligand from binding to the antigens, which are extensively presented in cancer cells. In addition, it can also affect enzymes by.......?You are saying that the inhibitor is competitive inhibitor. But according to data Vmax for reaction (with no inhibitor) is 4,17mM/min and Vmax for reaction (with inhibitor)=2,31mM/min. Then you show that Km for reaction with no inhibitor is 1.66. Then I calculate further for Km for reaction with inhibitor by using MM equation and I get 0,9. So both the Vmax and Km is reduced in reaction with inhibitor. That must mean the inhibitor is not competitive but non-competitive inhibitor. Or is it me that got it wrong??
