E) a phospholipid. 2) Whenever energy is transformed, there is always an increase in the A) free energy of the system. B) free energy of the universe. C) entropy of the system. D) entropy of the universe. E) enthalpy of the universe. 3) Which of the following is the most randomized form of energy? 4) Which of the following would decrease the entropy within a system? 5) Which of the following reactions could be coupled to the reaction ATP + H 2 O ADP + Pi (-7.3 kcal/mol)? 6) During a laboratory experiment, you discover that an enzyme-catalyzed reaction has a Δ G of +20 kcal/mol. You double the amount of enzyme in the reaction, and the G now equals Δ A) -40 kcal/mol. B) -20 kcal/mol. C) 0 kcal/mol. D) +20 kcal/mol. E) +40 kcal/mol. 7) For the reaction FUMARATE -> SUCCINATE, the G is +172 kcal/mol. Which of the following is FALSE? 8) The Keq is 3.0 for the reaction glucose -> glucose-1P. If the initial concentration of glucose is 0.8 M, at equilibrium what is the concentration of glucose-1P? The next questions are based on the following information. A series of enzymes catalyze the reaction X Y Z A. → → Product A binds to the enzyme that converts X to Y at a position remote from its active site. This binding decreases the activity of the enzyme. 9) Substance X is

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
