They do not depend on enzymes. b. They are usually highly spontaneous chemical reactions. They consume energy to build up polymers from monomers. c. d. They release energy as they degrade polymers to monomers. Which of the following is a statement of the first law of thermodynamics? ____ 3. 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. For living organisms, of the following is an important consequence of the first law of ____ 4. thermodynamics? a. The energy content of an organism is constant. b. The organism ultimately must obtain all of the necessary energy for life from its environment. c. The entropy of an organism decreases with time as the organism grows in complexity. d. Organisms are unable to transform energy. Life does not obey the first law of thermodynamics. e. Living organisms increase in complexity as they grow, resulting in a decrease in the entropy of an ____ 5. 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 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.
