< Question 7 of 10 > When the acetyl-CoA produced during $\beta$ oxidation in the liver exceeds the capacity of the citric acid cycle, the exce acetyl-CoA forms ketone bodies-acetone, acetoacetate, and D-$\beta$-hydroxybutyrate. This occurs in people with sever uncontrolled diabetes; because their tissues cannot use glucose, they oxidize large amounts of fatty acids instead. A acetyl-CoA is not toxic, the mitochondrion must divert the acetyl-CoA to ketone bodies. What problem would arise if acetyl-CoA were not converted to ketone bodies? Excess acetyl-CoA would convert into malonyl-CoA, promoting fatty acid synthesis. Accumulation of acetyl-CoA would activate glycolysis in the liver, leading to hypoglycemia. Accumulation of acetyl-CoA would deplete the mitochondrial CoA pool. Excess acetyl-CoA would inhibit the citric acid cycle and decrease the energy charge in the liver.

As with boiling points and melting points, solubility is chiefly determined by the intermolecular forces that exist between the solute and solvent when mixing occurs, vs. the forces found in the pure materials. Rank the solubility of NaCl in the following compounds and provide a clear explanation for your ranking. CH?CH?CH?CH?OH CH?NHCH? CH?CH(OH)CH?OH CH?CH?OH CH?CH?CH?OH CH?OH

Seth is a 64-year-old patient with a 10-year history of recurrent sinusitis. He presents to your primary care clinic today complaining of “head congestion.” He also reports that he had a “cold” last week with symptoms of cough and “runny nose.” Two days ago, he developed a headache that was “worse” when bending over but improved with Tylenol. He describes the headache as a “3 out of 10” and says it is primarily a “frontal headache.” He also reports that his nasal congestion has become worse; he has been blowing his nose even more; and the discharge from his nose has become thicker, with a yellow green color. He has been taking pseudoephedrine for the past 48 hours with little relief of her nasal congestion. He denies tooth pain or pain on chewing. He has no history of seasonal allergies, although he was treated for sinusitis 6 months ago in your clinic as well as approximately 1 year ago. The remainder of his medical history is essentially negative. His temperature taken at the clinic is 99.60F. On physical examination, he has tenderness to palpation in the frontal area, no maxillary tenderness, nasal mucosa is erythematous as is his pharynx. His submaxillary nodes are enlarged bilaterally, but there is no cervical lymphadenopathy. His lungs are clear to auscultation. His heart has a regular rate and rhythm and is negative for murmurs, gallops, and rubs. His vital signs are blood pressure 128/88; Pulse 78 and regular; Respirations 20 breaths/min, non-labored. 1. What is your assessment of Seth? 2. What is your plan of treatment? 3. Be sure to review the literature on sinusitis. What symptoms and signs are most indicative of a diagnosis of sinusitis? Which are not? How many of these symptoms/signs does Seth have? 4. What are some other things you might do to better assess Seth? 5. What are your therapeutic options? 6. What follow-up do you need to do on Seth?

Consider a function $f(x, y)$ at the point $(6, 4)$. At that point the function has directional derivatives: \frac{3}{\sqrt{65}}$ in the direction (parallel to) $(7, 4)$, and $\frac{6}{\sqrt{61}}$ in the direction (parallel to) $(6, 5)$. The gradient of $f$ at the point $(6, 4)$ is $(…, …)$.
