Print оr write this exаm using а pen оr dаrk pencil. Dоn't close this window until you're finished answering all of the questions. Open questions, for full credit show all of your work. 1. (15 points) You believe that a newly found antiporter transfers Na+ from the inside to the exterior and K+ from the exterior to the inside at 298K. The voltage is 62 mV higher in the exterior. The inside concentrations are 120 mM for K+ and 210 mM for Na+ and the exterior concentrations are 8 mM for K+ and 12 mM for Na+. For every two K+, three Na+ also are transported. a) What is the change in free energy for each Na+ alone b) What is the change in free energy for each K+ alone c) The overall change in free energy for the coupled transport is 2. (10 points) Explain what type of EPR signals you would expect to see for the Fe2+ and Fe3+ redox states of a heme in a protein. 3. (10 points) A protein has a measured to have a 2D NMR spectrum. When a small molecule was added to the protein solution, the 2D spectrum changed, with some peaks shifting while others did not change. Interpret these results in terms of a potential role of the small molecule in altering the protein’s function. 4. (15 points) Suppose someone comes to you and states that they had found a new amino acid. You say that you will identify the amino acid using NMR. The observed 2D NMR spectrum is below. Determine the structure of the new amino acid. For full credit label all of the peaks and include an explanation of why you believe this would be the spectrum.
