QUIZ: CELLULAR RESPIRATION Name ______________________________________________ Date ______________ Period _________ Group! QUIZ: CELLULAR RESPIRATION Directions: This is a group quiz that you will take using your QuizKit. The purpose of this quiz is to give you a whole bunch of fun visuals to better understand the elegant process of cellular respiration, and to help you review what you’ve already learned. Make your responses directly on this quiz, and leave no questions blank. Make sure that your answer addresses what the question is asking. For a question which needs teacher initials, you must obtain them to get credit for the question. You may use your notes to help you! Every person in the group gets the same grade, so work together! Good luck, have fun, now go forth and do science! 0. What is the best kind of cake to have in the morning? 1. What is the overall purpose of cellular respiration? 2. What are two types of reduced compounds that can carry electrons to the electron transport chain? 3. Which phase of cellular respiration makes the most ATP? 4. Using the materials in your QuizKit, and your brains (which, I’d wager, are just swollen with knowledge by now), make a model of a cell with a single, large mitochondrion. The edge of the lab bench should be the cell membrane. Make sure you label the cell membrane, mitochondrial inner membrane, intermembrane space, cytoplasm and mitochondrial outer membrane. 5. Put the three main sections of cellular respiration in the cell in their correct positions. That is, I want you to model where each process occurs. 6. What process pumps protons across the mitochondrial inner membrane, and stores them in the intermembrane space? 7. What do you call a molecule that has gained an electron? Lost an electron?

8. Using the materials in your QuizKit, make a model of glucose. N. B 8. Using the materials in your QuizKit, make a model of glucose. N.B. – it is not necessary to include all the atoms, just the carbon. You should make a chain of carbon that is six carbons long. 9. Move your carbon through glycolysis, and simulate what would happen to it. 10. Why do you exhale carbon dioxide? 11. Why do you need to breathe in oxygen? 12. Move one of your two molecules of pyruvate through the Krebs Cycle. You should demonstrate the following steps. Get the initials when you are all finished. Loosing a molecule of carbon dioxide to make Acetyl CoA Combination with oxaloacetate Making some ATP Making some reduced compounds Loosing two more molecules of carbon dioxide Regeneration of oxaloacetate 13. The NADH and FADH2 molecules that are produced in the first two steps of cellular respiration carry electrons. They then dump the electrons into the electron transport chain. These electrons fall, and release energy to pump protons. Demonstrate the movement of protons with the materials in your quiz kit. 14. What does ATP synthase produce, in copious amounts? 15. The E.T.C. creates a proton gradient. These protons move down their gradient, through an enzyme called ATP synthase. Demonstrate this using your QuizKit.
