2,3 Bisphosphoglycerate: a) binds to the central cavity of the fully deoxygenated hemoglobin protein in order to stabilize the deoxygenated form of the protein in respiring tissues. b) binds to the central cavity of the fully oxygenated hemoglobin protein in order to stabilize the oxygenated form of the protein in the lungs. c) competes with O2 for heme binding and as a result shifts the oxygen saturation curve towards the deoxygenated form. d) binds to each hemoglobin subunit and as a result shifts the oxygen saturation curve towards the deoxygenated form. This phenomenon is known as the Bohr Effect.

Exercise: For the lossless transmission line presented in Figure 21.1, find the load voltage $V_L$. Write a MATLAB program to plot the load voltage $V_L$ vs time. Is the magnitude of the load voltage $V_L$ a function of source frequency $f$? If it is, plot $|V_L|$ vs $f$; if not, explain. $Z_s = 100 \Omega$ $60\angle 0^\circ V$ $f = 25 \text{ MHz}$ $Z_0 = 50 \Omega$ $v_p = 2.0 \times 10^8 \text{ m/s}$ $Z_L = 200 \Omega$ $l = 2.0 \text{ m}$

2. Model the following mass-spring system. Make sure to select your coordinates, draw the free-body diagram(s), and derive the final equations of motion. Simplify your final answer as much as possible. • Do not model friction, nor gravity. The system is capable of moving in the horizontal direction only. • $k_1 = \frac{13 N}{m}$ • $k_2 = \frac{6 N}{m}$ • $m = 20 kg$ 3. For problem #2, calculate the change in potential energy of each spring. Spring #1's initial displacement was 0.34 m, and spring #2's final displacement was 0.15 m.
