Q19 In order to find bactericidal antibiotics – substances that can selectively kill bacteria without harming human cells, a combinatorial library was screened in 96 well plates. Which of the five compounds (I - V) is the most likely to be a bactericidal antibiotic? Choose one answer only. | || ||| IV v Bacterial cells and compounds Bacterial cells only Human cells and compound Human cells only a. V b. III c. II d. I cell growth no cell growth

A 23-year-old woman with a history of asthma was brought to the emergency department by ambulance. She was extremely short of breath. Her level of consciousness was diminished greatly, and she was only able to respond to questions with nods or one-word responses. She had a weak cough, with nearly inaudible breath sounds. After drawing blood gases, she was placed on supplemental oxygen. Vital signs: heart rate, 160 bpm; blood pressure, 120/84 mm Hg; temperature, 37°C; and respiratory rate, 36/min. Her initial blood gas and total hemoglobin results were as follows: pH = 7.330 pCO2 = 25 mm Hg pO2 = 58 mm Hg HCO3 = 13 mmol/L tHb = 12.4 g/L QUESTIONS: 4. What clinical findings are most indicative of this patient’s impending failure?

CK (38 -174 U/L normal range) and CK-MB (0- 24 U/L normal range) assays: give 3 or more examples of diseases or circumstances that could cause patient results outside the expected range. The CK-MB reagent contains the chemical components for the same enzymatic reactions that the CK reagent does. Explain briefly how we are able to measure only the CK-MB activity with the CK-MB kit.

The enzyme urease increases the rate of urea hydrolysis at pH 8.0 and 20 °C by a factor of 1014. Suppose that a given quantity of urease can completely hydrolyze a given quantity of urea in 19 minutes at pH 8.0 and 20 °C. How long would it take for this amount of urea to be hydrolyzed in the absence of urease at the same temperature and pH in sterile conditions? Include two significant figures in your answer. timeuncatalyzed years * TOOLS x10

What do you predict the addition of an acid will have on catalase? Will it increase, decrease, or have no effect on the chemical reaction between hydrogen peroxide and catalase?

Which of the following is the correct Ksp expression for Al2(SO4)3(s)? OKsp [A1³+12[SO4²-1³ = Ksp = [2A1³+][3SO42-1 OKsp = ([A1³+12[SO4²-1³) / [Al2(SO4)3] Ksp [A13+12+ [SO4²-1³ =

The acid-catalyzed hydrolysis of sucrose, C12H22O11 + H₂O + H+ -> C6H12O6 + C6H12O6 + H+ is known as "inversion of sucrose" because the angle, a, by which the solution rotates polarized light changes from positive to negative as the reaction proceeds (data from 30 degree C): t/hr a 0 78 2 71 4 12 18 24 42 65.10 44.60 32.40 22.45 2.30 48 -1.96 61 -9 86 95 -15.80 -17.25 -21.15 ∞ Use this data to show that the reaction is first order and determine its rate coefficient (at 30 degree C).

Complete each of the following chemical reactions.

Dangerous Paint Stripper Jessica has a summer job working for the city parks program. She has been using a cleaner called “Graffiti Gone” to remove graffiti from the bathrooms. She has to take a lot of breaks, because the chemical makes her throat burn. It also makes her feel dizzy sometimes, especially when the bathrooms don’t have very many windows. On the label, she sees that the cleaner has methylene chloride in it. She feels like she’s managing to get the work done, but she is worried about feeling dizzy. She wants to find out more about this chemical, what harm it can cause, and whether there are safer ways to do this work. Questions for following story. 1. What went right in this situation? 2. What went wrong in this situation? 3. What steps should be taken in this workplace to make sure employees are better protected and prepared the next time?
