Chemistry 5 grams of cereal was crushed and dissolved in 25 mL water and placed in a dialysis bag. This sample was dialysed over a week in a beaker which contains 500 mL of water. 5 mL of the dialysate (an aliquote from the 500 mL) was separated to determine the glucose concentration. The glucose concentration was determined as 5 mM. Calculate the amount (% w/w) of glucose present in the cereal. Hint: The molecular weight of glucose is 180.

You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.

Calculate the theoretical yield of 2mL of vegetable oil saponification reaction with 2mL of 6M NaOH and 40mL of saturated salt solution(NaCl).  GIVENS: density of the oil = 0.9 g/mL  each fatty acid side chain of the oil has 18 C atoms (C_18: the carbonyl carbon, plus a C_17 carbon chain). Assume an average of one unsaturation per side chain.

Chemistry You are the only doctor in a clinic that is cut off from the outside world by violent storms and landslides. A 30-year-old woman suffering from tachycardia is brought in. You can see she is likely to die without treatment, and although you have very few drugs, you have propranolol, a beta blocker, in injectable vials. You decide to give the woman intravenous propranolol. The pharmacokinetics of propranolol include a clearance of 50L/hour and a half-life of 3 hours. If an intravenous infusion of propranolol is started at a rate of 0.5mg/minute, approximately how long would it take to reach 93.75% of the final steady-state concentration? 3 hours 50 minutes It would depend on the dosage 12 hours

A research group discovers a neW version oI happyasee, which they nappyase", that catalyzes the chemical reaction HAPPY = SAD The researchers begin to characterize the enzyme. In the first experiment, with [E] at 4 nM, they find that the Vmax is 1.6 µM s-1. Based on this experiment, what is the kcat for happyase*? kcat 400 S In another experiment, with [E,] at 1 nM and [HAPPY] at 30 µM, the researchers find that Vo is equal to 300 nM s-1. What i the measured Km of happyase* for its substrate HAPPY? Km 10 x10–6 Incorrect Further research shows that the purified happyase* used in the first two experiments was actually contaminated with a reversible inhibitor called ANGER. When ANGER is carefully removed from the happyase* preparation, and the two experiments repeated, the measured Vmax increases to 4.8 µM s-, and the measured Km is now 15 µM. S For the inhibitor ANGER, calculate the values of a' and a. a' 2 Incorrect 2
