C485 Exam I Fall ‘09 Do not use acronyms. Use structures whenever they are asked for, or appropriate. Your explanations should be brief . Overly lengthy answers with irrelevant or erroneous material will receive deductions. GOOD LUCK 1. (10 Pts) Consider enzyme catalysis completely from the perspective of binding. Name two strategies an enzyme could use to achieve catalysis. Draw a notional free energy profile depicting these. (You should draw a starting profile and then show what results when you apply the strategy you have selected.) 2. (4pts) What is the overall redox reaction catalyzed by PSll? 3. (4 pts) There are two mobile electron carriers in photosynthesis that carry electrons between the three major components (PSI, Cytochrome bf and PSII), please name them. 4. (8 pts) Draw the mechanism for how the mobile electron carrier between PSII and Cytochrome bf undergoes reduction (use chemical structures).
