As a first test of this drug, you grow the bacteria in the presence of different concentrations of this drug and analyze its effect on the growth of the bacteria. The data are shown in the table below listing the drug concentration in milliMolar (mM) against the percentage of growth relative to the control (no drug). Construct an appropriate graph for the presentation of these data. Drug Concentration (mM) Percentage of Growth (%) 0 100 1 83 2 76 3 62 4 55 5 30 6 15 7 2

- A biologics production process uses a series of vats to make pharmaceuticalproducts. Each vat contains a mixture of compounds and live organisms (e.g., bacteria) andmust be strictly controlled in terms of temperature, acidity, and other factors.

- 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.......?E-strip testing can be used to determine a drug MIC against an organism. Which ONE of the following is correct? Select one: A. The zone of inhibition is inversely proportional to the activity of the drug B. The E-strip result guides to the maximum drug concentration that can be used to clear an infection C. The E-strip is impregnated with a fixed concentration of drug D. The E-strip is used broadly clinically to determine if an organism is resistant to a drug E. The MIC is read where bacterial growth touches the E-stripPenicillin heralded the dawn of the antibiotic age when it was discovered in 1928 and is now the most widely used antibiotic in the world. A membrane electrode was developed for the quantitative analysis of penicillin. The table above shows the data which were collected using a set of penicillin standards against saturated calomel electrode. An unknown sample produced a potential of 142 mV. A) Which served as the reference electrode? B) What is the molar concentration of penicillin in the sample?
