Short Answer Questions - Each total question is worth 10 points. So the total is 20 points for questions 51 and 52. 51. Prepare 2 Liters of a 4 molal (be careful with the terminology - I am asking for molality, not molarity) solution of MgSo. (Magnesium Sulfate) in water. Magnesium Sulfate is a medication used to prevent seizures in a condition termed preeclampsia in pregnancy. The MgSo. is the solute and water is the solvent. YOU CAN USE THE PERIODIC CHART FOR AMUs on the chemistry Inorganic PowerPoint file-slide 22 or you can look up the atomic weights on the internet. Use rounded numerical atomic weights instead of exact ones with decimal values. A. How much MgSO4 should be weighed out? B. How many molecules of MgSO4 are in the solution? C. How many individual atoms of solute are present? D. How much water should be added?

Substance A is the initial precursor substance. Enzyme 1 assists in the conversion of substance A to substance B and likewise enzyme 2 converts substance B to C: enzyme 3 assists the conversion of substance C to D. The final product, substance D can act as a competitive inhibitor on enzyme 1 if the concentration of substance D gets out of homeostatic range. Remember brackets around a chemical mean concentration of that chemical. Questions A. Explain the induced fit aspect of enzymology? B. If an iron atom is needed to cduse enzyme 1 to work, it would most likely be called a ----- for that enzyme. C. What is reversible competitive inhibition? D. If substance D could not fit into enzyme's 1 active site, would that mess up homeostasis? Explain-Do not just say yes or no, you must explain to get any credit.
