Which of the following is TRUE regarding the Electron Transport Chain? A. During the steps of the Electron Transport Chain, electrons and H+ ions from NADH and FADH2 are transferred to ADP to form ATP by Oxidative Phosphorylation. B. During the steps of the Electron Transport Chain, electrons and H+ ions from NADH and FADH2 are transferred to ADP and phosphate to form ATP by Substrate Phosphorylation. C. During the steps of the Electron Transport Chain, electrons and H+ ions from NADH and FADH2 are transferred to Oxygen, and ATP is generated by Oxidative Phosphorylation. D. During the steps of the Electron Transport Chain, NADH and FADH2 are oxidized to form Oxygen and ATP through Oxidative Phosphorylation. Question 9 (1 point): Which of the following is TRUE regarding Pyruvate Decarboxylation? A. The products of Glycolysis are further oxidized to give three 2-carbon Acetyl-CoA molecules and two NADH molecules from each original 6-carbon sugar molecule. B. The products of Glycolysis are further oxidized to give two 2-carbon Acetyl-CoA molecules, two NADH molecules, and two CO2 molecules from each original 6-carbon sugar molecule. C. The products of Beta Oxidation are further oxidized to give two 2-carbon Acetyl-CoA molecules and two NADH molecules from each 6-carbon section of the original Fatty Acid. D. The products of Beta Oxidation are further oxidized to give two 2-carbon Acetyl-CoA molecules and two CO2 molecules from each 6-carbon section of the original Fatty Acid. Question 10 (1 point): Which of the following is TRUE regarding Ketones? A. Ketones are formed from Acetyl-CoA through Ketogenesis, easily diffuse across cell membranes, and transfer metabolic energy between different cells and organs. B. Ketones are a toxic waste product of anaerobic metabolism. When they are produced during ketogenesis, they must be converted to Glucose through the Cori-Cycle, at the cost of 6 molecules of ATP for each ketone. C. Both Acetyl-CoA and Ketones are transported in the blood; however, Ketones are unable to cross the blood-brain barrier. As such, Acetyl-CoA must first diffuse into the brain and then be used to form Ketones through.

Exercise 6-63 (Algorithmic) Inventory Costing Methods: Periodic Inventory System (Appendices 6B) The inventory accounting records for Roth Corporation contained the following data: Beginning inventory 400 units at $10 each Purchase 1, Feb. 26 2,300 units at $14 each Sale 1, March 9 2,500 units at $27 each Purchase 2, June 14 2,200 units at $15 each Sale 2, Sept. 22 2,100 units at $29 each Required: Calculate the cost of ending inventory and the cost of goods sold using the FIFO, LIFO, and average cost methods. (Note: Use four decimal places for all other numbers to the nearest dollar.) FIFO LIFO Average cost Cost of ending inventory 4,500 3,000 4,236 Cost of goods sold 64,700 66,200 64,963

3. (20 points) (Sparsity) Assume we have: ? = \begin{bmatrix} 1 & 1/\sqrt{2} & 0 & -1/\sqrt{2} \\ 0 & 1/\sqrt{2} & 1 & 1/\sqrt{2} \end{bmatrix} (a) (10 points) Suppose that for some fixed b ? R$^2$, the equation ?x = b has a 1- sparse solution. Show this solution is unique, and so we can recover any 1-sparse solution x ? R$^4$. (b) (10 points) Let b a vector in R$^2$. Show that the equation ?x = b can have as many as six distinct 2-sparse solutions.

Exercise 1.21. This illustration of $I^2R$ heating may help you understand the disadvantage of the center-tapped rectifier circuit. What fuse rating (minimum) is required for passing the current waveform shown in Figure 1.64, which has 1 amp average current? Hint: a fuse \"blows out\" by melting a metallic link ($I^2R$ heating), for steady currents larger than its rating. Assume for this problem that the thermal time constant of the fusible link is much longer than the time scale of the square wave, i.e., that the fuse responds to the value of $I^2$ averaged over many cycles.
