2. Remember…. correct C = You know this is the correct answer unsure U = you think this is the correct answer but are unsure guessed G = You guessed

3. 1.Which of the following does NOT describe a polymer? A.Polymers are large molecules B.Polymers are made of only one sub unit C.Polymers are made of monomers D.Polymers are made of many smaller units

4. 2.Identify this structure A.Carbohydrate B.Lipid C.Protein D.None of the Above

5. 3.Which of the following is the major function of Lipids? A.Pass on genetic information B.Catalyze chemical reactions C.Long term energy storage D.Provide quick energy

6. 4.Which of the following is the major function of carbohydrates? A.Pass on genetic information B.Catalyze chemical reactions C.Long term energy storage D.Provide quick energy

7. 5.Enzymes can be destroyed when pH or temperature are outside the normal range. If this happens, which characteristic of life is most affected? A.Evolution B.Homeostasis C.Reproduction D.Growth and development

8. 6.During digestion food must be broken down into smaller molecules for use by the body. Which type of biomolecule does this job? A.Carbohydrates B.Lipids C.Nucleic acids D.Proteins

9. 7.An enzyme inhibitor binds to the active site on the enzyme, thus blocking the substrate from binding to the enzyme. How would this effect the rate of reaction? A.The reaction would slow B.It would keep the reaction rate constant C.The reaction would speed up D.It would cause the reaction to go in reverse

10. 8.What will most likely happen if an appropriate enzyme is added to a chemical reaction? A.The equilibrium of the reaction will be maintained B.The reaction rate will increase C.The reaction rate will decrease D.The reaction will stop

11. 9.In the figure above which letter represents a reaction that is occurring with an enzyme? A.A B.B C.C D.D

12. 10. Fireflies emit light. The production of light by an organism is called bioluminescence. To generate visible light, cells in a firefly’s tail produce thousands of luciferase enzymes. Luciferase binds to a chemical called luciferin. Once bound, the luciferase enzyme speeds up a chemical reaction that combines an oxygen molecule and luciferin to produce oxyluciferin. This reaction requires energy and releases light. Which of the following best describes how the luciferase enzyme speeds up the chemical reaction? A.Luciferase increases the amount of time the light is visible. B.Luciferase decreases the amount of energy required for the reaction to start. C.Luciferase increases the number of sites on luciferin that must bind to the oxygen D.Luciferase decrease the temperature of the environment inside the body of the firefly.
