Exam II Biology 110 -- Fall 2007 Drs. Bos, Meyer and Wang INSTRUCTIONS:   Please be sure to fill in your BIOL 110 code number and  NOT  your SSN or  Purdue ID in the section of the scantron sheet marked: Student Identification Number. The  use of calculators, cell phones or other electronic devices is not allowed during the exam.  There are 33 questions in this exam.  Read each question carefully and choose the best  answer.  Do not fill in multiple answers because they will be marked incorrect. Turn in only  the answer sheet when you are done. You may keep the exam. Take your time, think  carefully and good luck! 9.If a chemical reaction in a cell is measured and found to have a negative Gibbs free energy value (- G),  it means that ______________________. A. enthalpy (H) is increasing B. the reaction is not spontaneous C. the reaction is endergonic D. the reaction is exergonic E.  it has no meaning with regard to chemical reactions 10. In many biochemical reactions within the cell, even if they are exergonic, they will not proceed  unless some energy is first put into the system to start the reaction.  We call this “activation  energy”.  There are substances within the cell that lower  the activation energy and facilitate these  reactions.  We call these substances ________________. A. activators B. enzymes C. facilitators D. detractors E. energizers 11. Note the free energy changes for the following chemical reactions.   Reaction #1  G = - 9 kcal/mole Reaction #2  G = + 5 kcal/mole Reaction #3  G = + 10 kcal/mole Reaction #4  G = +4 kcal/mole Reaction #5  G = 0 kcal/mole

Given just the free energy changes, which two reactions could be coupled together to produce a  reaction that favors the products? A. Reaction #1 and Reaction #4. B. Reaction #1 and Reaction #3. C. Reaction #2 and Reaction #3. D. Reaction #3 and Reaction #4. E. Any of the first four reactions coupled with #5 will produce a reaction that favors the  products. 12. Which of the following is true of endergonic reactions? A. They create energy that did not exist before the reaction took place. B. The equilibrium state of an endergonic reaction favors the products. C. The total energy (H) of the system undergoing an endergonic reaction increases. D. The free energy of the products is greater than the free energy of the reactants. E.
