Unformatted text preview: MCB 102 University of California, Berkeley July 21-23, 2009 Isabelle Philipp Handout Problem Set 5 The answer key will be posted by Friday July 24 . Try to solve the problem sets always first without the answer key. Remember, your goal is to be able to solve biochemical problems in the exams. If you can not solve one of the problems try to solve it together with one of your classmates or ask your GSI during discussion section. Don’t just wait for the answer key. The answer key should only confirm that you solved the problem correctly! Exercises and Problem Sets are for extra practice and exam preparation, and should not be turned in. Recommended problems from the book: • Chapter 13: 2, 3, 4, 5, 6, 9, 11, 12, 14, 15 • Chapter 19: 1, 3, 4(!), 15, 16, 19, 26, 34, 35, 36, 37, 41 • Chapter 21: 1, 3, 7, 8 1. Match the K eq values with the appropriate Δ G o values K eq Δ G o (kJ/mol) a) 1 i) 28.53 b) 10- 5 ii) –11.42 c) 10 4 iii) 5.69 d) 10 2 iv) e) 10- 1 v) –22.84 2. Energy conservation The complete combustion of glucose to CO 2 + H 2 O proceeds with an overall Δ G o ’ of –2863 kJ/mol. When this process occurs in a typical cell, 32 moles of ATP are produced from ADP + P i . Assuming that cellular Δ G for ATP → ADP hydrolysis is –41.7 kJ/mol and that Δ G ∼ =Δ G o ’ for glucose oxidation under intercellular (in vivo) conditions, what fraction of the potential energy of glucose is conserved in the form of...
