Problem set 4: All problems are assigned from the 6 th edition of biochemistry by Stryer et al. Chapter 18: Oxidative Phosphorylation pg 539-540: 1 (all but e), 2, 4, 5, 7, 10, 13-15, 18. Note: #5. Oligomycin blocks ATP synthase, Rotenone blocks electron transfer from complex I to coenzyme Q. The answer diagrammed in the student companion is incorrect. #7. Again assume the value of the FAD-FADH 2 is 0V (even though the table says – 0.22V)… and no, you do not have to memorize table 18.1. #13. Read the question carefully and determine what it is asking.
