6. Emphysema results from loss of elasticity (elastic fibers and other connective tissue proteins) in alveolar walls of the lungs, so CO$_{2}$ can't be exhaled effectively, so there isn't room for inhaling much fresh air (O$_{2}$). Neutrophils (white blood cells that engulf invading bacteria) secrete elastase. The excess elastase in blood plasma can hydrolyze elastic fibers in alveolar walls of the lungs and resulting in emphysema. To prevent elastase from running amok in plasma, liver makes and secretes a plasma protein, $\alpha_{1}$-antiproteinase (also sometimes referred to by its old name, $\alpha_{1}$-antitrypsin), which in blood plasma keeps elastase inhibited, protecting lungs from damage. Components of cigarette smoke oxidizes a Met residue in $\alpha_{1}$-antiproteinase that's required for binding to elastase (oxidation $\rightarrow$ non-functional inhibitor). Smokers continually inactive $\alpha_{1}$-antiproteinase in the blood plasma in their lungs and thus are also much more likely to develop emphysema. Consider if there would be a mutant $\alpha_{1}$-antiproteinase that would be more resistant to oxidation than the naturally occurring inhibitor, and thus might make an individual with that mutation less susceptible to emphysema? What kind of amino acid substitution might have that effect, and why?

2. Pulling apart a capacitor. Imagine that you have a parallel plate capacitor whose plates have an area A and are separated by a distance d. One plate has a charge Q and the other a charge -Q. Treat the fields as though the plates were infinite. a. What is the electric force on each plate, due to the other plate? b. If you pull the plates farther apart, so that their separation increases from d to 2d, how much work have you performed? c. What is the change in the total energy in the capacitor, written in terms of Q, A, and d? Does the answer make sense?

4. Determinants of security values For decades in the U.S., street vendors have popped up in densely populated areas, such as major cities, beaches, and festivals. These businesses sell things from hamburgers and hot dogs to tacos and Mexican street corn. After the recession hit between 2008 and 2009, the U.S. saw an increase in the number of mobile food businesses, namely an increase in the number of food trucks. Because this is the first time this industry has seen this much growth, suppose investors look carefully at historical food truck financial records, customer feedback, and any other information they can get their hands on to give them better insight into the industry's potential performance. After investors review this information, suppose they determine that there is a high likelihood of the businesses generating high cash flows, and thus a high return on their investment, and they revise their valuations of the stocks accordingly. True or False: Given the scenario, the investors are using firm-specific information to take their positions on the security. True False Use the graph to show what happens to the supply, demand, and equilibrium price in the market for food truck stocks in the short run, assuming that if supply and demand change, they do so simultaneously.
