Intermediate E is an allosteric inhibitor of enzyme 2. Explain how an allosteric inhibitor controls enzyme function. [3-4 sentences] Describe how the pathway is affected when the cell has initial reactant, but no intermediate E. In other words, what happens to enzyme 2 and what happens to the overall function of the pathway? [3-4 sentences] Intermediate C is an allosteric activator of enzyme 5. Explain how an allosteric activator controls enzyme function. [3-4 sentences] Describe how the pathway is affected when the cell has initial reactant, and lots of intermediate C. In other words, what happens to enzyme 5 and what happens to the overall function of the pathway? [3-4 sentences] • Note this question is distinct from and not reliant on the information in question 4.a.ii. c. You develop an antimicrobial drug that blocks the binding of intermediate C to enzyme 5. Answer the following: Explain how the function of enzyme 5 changes in the presence of the drug. Assume the cell has initial reactant. [2-3 sentences] Describe how the pathway is affected by the drug. In other words, what happens to the enzymes in the pathway and what happens to the overall function of the pathway? [3-4 sentences]

Texts: Student loan debt is an emerging social problem for the current generation of young adults. Some data suggest that among those with debt, outstanding student loan debt in 2010 was around $25,000. Scholars have suggested that for-profit institutions (e.g. DeVry; ITT-Tech) are key contributors to rising student loan debt, as they tend to be far more expensive than non-profit institutions, offer less aid, and their graduates do not fare as well in the labor market as graduates of non-profit institutions. Your goal in this exercise is to test this hypothesis. To do so, you draw a random sample of 4,000 college graduates in the United States. After collecting your data, you find that students who graduated from for-profit institutions (N=2,200) reported, on average, $45,000 in outstanding student loan debt (SD=$12,000). By contrast, graduates from non-profit institutions (N=1,800) reported an average of $12,000 in outstanding student loan debt (SD=$3,000). Complete the questions below and come to a conclusion about the association between institution type and student loan debt. Use an alpha of .05 for your hypothesis test. What type of hypothesis test (test statistic) will you use and why? Is this a one- or two-tailed test? Why? Formally state your hypotheses (remember there are always two hypotheses) that you will test. State your hypotheses in words as well. What is the critical value of the test statistic? What is the obtained value of the test statistic? What is your decision about the null hypothesis? Please provide an interpretation of your results.

3. Consider a homogeneous gas phase reaction A \rightarrow 3B r = kc_A^2 For a feed rate of 4 m³/hr of pure A at 5 atm and 350 °C, a pilot reactor consisting of a 2.5 cm ID pipe 2 m long gave 60% conversion of feed. A commercial plant is process 320 m³/hr of feed consisting of 50% each of A and inerts at 25 atm and 350 °C, and 80% conversion is required. Find how many 2 meter lengths of 2.5 cm ID pipe are needed. Should they be placed in series or parallel? (Ans: From pilot plant data we can find the rate constant $k = 2.04 \times 10^5$ L/mol h. Approximatley 68 tubes needed)
