E A B C D E 2. Which of the following is a statement of the first law of thermodynamics? a. Energy cannot be created or destroyed. b. The entropy of the universe is decreasing. c. The entropy of the universe is constant. d. Kinetic energy is stored energy that results from the specific arrangement of matter. e. Energy cannot be transferred or transformed. A B C D E 3. Living organisms increase in complexity as they grow, resulting in a decrease in the entropy of an organism. How does this relate to the second law of thermodynamics? a. Living organisms do not obey the second law of thermodynamics, which states that entropy must increase with time. b. Life obeys the second law of thermodynamics because the decrease in entropy as the organism grows is balanced by an increase in the entropy of the universe. c. Living organisms do not follow the laws of thermodynamics. d. As a consequence of growing, organisms create more disorder in their environment than the decrease in entropy associated with their growth . e. Living organisms are able to transform energy into entropy. A B C D E 4. Which of the following statements correctly describe(s) some aspect of energy in living organisms? a. Living organisms can convert energy among several different forms. b. Living organisms can use energy to do work. c. Organisms expend energy in order to decrease their entropy d. A and B only e. A, B, and C A B C D E 5. Which of the following forms of energy is least available to accomplish cellular work? a. light energy b. electrical energy c. thermal energy (heat) d. mechanical energy e. potential energy A B 6. Which of the following is true for all exergonic reactions?

C D E a. The products have more total energy than the reactants. b. The reaction proceeds with a net release of free energy. c. Some reactants will be converted to products. d. A net input of energy from the surroundings is required for the reactions to proceed. e. The reactions are nonspontaneous. A B C D E 7. Why is ATP an important molecule in metabolism? a.
