Question 3. (6 points total) One of the most important reactions in cellular metabolism is the hydrolysis of adenosine triphosphate (ATP) to adenosine diphosphate (ADP) and inorganic phosphate (P) according to the reaction ATP(aq) + H2O(l) ADP (aq) + P₁(aq) Using the following information from the hexokinase catalyzed phosphorylation of glucose (Gluc) to glucose-6-phosphate (G6P) and the phosphatase catalyzed hydrolysis of G6P to Gluc and Pi: Gluc(aq) + ATP(aq) G6P(aq) + ADP(aq) ΔGHK = -17.83 kJ mol-1 G6P(aq) + H2O Gluc(aq) + P₁(aq) AG = ? Kp aGluc[Gluc]eq* ap, [Pi]eq AG6P [G6P]eq Where a are the activity coefficients for the respective species. Useful thermodynamic data follow: Equilibrium concentrations and activity coefficients for G6P, Pi, and Gluc at 298.15 K and pH 7.

a. The minimum variance portfolio contains at least three securities. b. The minimum variance portfolio is the single security with least total risk. c. The minimum variance portfolio is dominated by the risk-free rate. d. The minimum variance portfolio has the least total risk. LL has 20 million shares of stock trading at $12 per share. Security analysts estimate LL’s beta to be 1.25. The risk-free rate is 5.5% and the market risk premium is 4%. LL’s capital structure is 20% financed with debt at an 8% interest rate; any additional debt due to the acquisition also will have an 8% rate. LL has a 25% federal-plus-state tax rate, which will not change due to the acquisition. The following data incorporate expected synergies and required levels of total net operating capital for LL should Hager’s complete the acquisition. The forecasted interest expense includes the combined interest on LL’s existing debt and on new debt. After 2028, all items are expected to grow at a constant 6% rate.
