Regarding alcohol abuse, which of the following statements is FALSE? Binge drinking is considered four or more drinks in a short time for men and three or more for women. Research has shown that teenagers and young adults who drink heavily may lose as much as 10 percent of their brain power, particularly in areas related to memory. One American dies every 20 minutes in an alcohol-related car crash. Relatives of those who abuse alcohol are at greater risk for becoming alcohol abusers themselves.

g) What mathematical feature of your profit function is the break-even point? h) You, being a good business owner, want to do better than simply break even. How many gizmos should you produce in order to maximize your profit? Show how you would find this point algebraically, then check your work with a graphing calculator. i) A colleague of yours says, "Look kid, I went to business school, and let me tell you, all this fancy math stuff is just quackery. If we produce 500 gizmos, we'll produce more stuff, and make more money. Stop trying to change how we do things around here!" Explain, mathematically and professionally, why your colleague is incorrect.

7. You have engineered a protease to catalytically break the backbone amine bond of a peptide (histidine-alanine-glutamine) substrate. The substrate binds to the enzyme active site only if the substrate's histidine is positively charged. Conversely, an aspartic acid residue in the enzyme's active site must be negatively charged to enable binding. a. Draw a schematic of the reaction mechanisms. b. Derive an expression for the rate of product formation as a function of rate constants and concentrations of total protease, unbound peptide (in either protonation state), and H+. c. Plot the initial reaction rate as a function of pH for the following parameter values: • Protease-substrate association rate constant = $10^6M^{-1}s^{-1}$ • Protease-substrate dissociation rate constant = $2s^{-1}$ • Catalytic turnover number = $10s^{-1}$ • Total enzyme concentration = 1 nM • Unbound peptide concentration = 2µM d. What pH yields the maximum reaction rate? (Hint: (a) The binding event occurs only between $E^-$ (carboxyl group deprotonated) and $SH^+$ (histidine group protonated). You can write the usual enzymatic reaction between these an enzyme and a substrate except that it involves these two species. (b) Solve for $[E-SH^+]$ using QSSA. But you should remember that $[E^-]$ is in equilibrium with $[EH]$ and $[H^+]$, and that $[SH^+]$ is in equilibrium with $[S]$ and $[H^+]$. Then you can write an equation for $rac{d[P]}{dt} = k_{cat}[ES]_{QSSA}$ (c) You will need $pK_a$ values for aspartic acid and histidine. Use 3.90 and 6.04, respectively. (d) You should differentiate $rac{d[P]}{dt}$ with respect to $[H^+]$ and set that to zero and solve for $[H^+]$.)

4. A shaft is loaded in bending and torsion such that Ma =70 N/m, Ta =45 N/m, Mm = 55 N/m, and Tm = 35 N/m. For the shaft, Su =700 MPa and Sy =560 MPa, and a fully corrected endurance limit of Se =210 MPa is assumed. Let Kf =2.2 and Kfs =1.8. With a design factor of 2.0 determine the minimum acceptable diameter of the shaft using the (a) DE-Gerber criterion. (b) DE-ASME Elliptic criterion. (c) DE-Soderberg criterion. (d) DE-Goodman criterion. Discuss and compare the results.

Required information A fluid between two very long parallel plates is heated in a way that its viscosity decreases linearly from 0.90 Pa\s at the lower plate to 0.50 Pa\s at the upper plate. The spacing between the two plates is 0.4 mm. The upper plate moves steadily at a velocity of 10 m/s, in a direction parallel to both plates. The pressure is constant everywhere, and the fluid is Newtonian and assumed incompressible. Neglect gravitational effects.
