PRACTICE TESTS (CHAPTER 9) CELLULAR RESPIRATION: HARVESTING CHEMICAL ENERGY 1. A molecule becomes more oxidized when it _____. ( Concept 9.1 ) - loses a electron 2. In the overall process of glycolysis and cellular respiration, _____ is oxidized and _____ is reduced. ( Concept 9.1 ) - glucose; oxygen 3. Most of the ATP produced in cellular respiration comes from which of the following processes? ( Concept 9.1 ) - oxidative phosphorylation 4. Oxygen gas (O 2 ) is one of the strongest oxidizing agents known. The explanation for this is that _____. ( Concept 9.1 ) - the oxygen atom is very electronegative 5. The function of cellular respiration is to _____. ( Concept 9.1 ) - exact usable energy from glucose 6. During the reaction C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O, which compound is reduced as a result of the reaction? ( Concept 9.1 ) - exact usable energy from glucose 7. Which of the following statements provides the best explanation for why the oxidation of organic compounds by molecular oxygen (O 2 ) yields so much energy? ( Concept 9.1 ) - oxygen 8. Each ATP molecule contains about 1% of the amount of chemical energy available from the complete oxidation of a single glucose molecule. Cellular respiration produces about 38 ATP from one glucose molecule. What happens to the rest of the energy in glucose? ( Concept 9.1 ) 9. A small amount of ATP is made in glycolysis by which of the following processes? ( Concept 9.1 ) 10. A chemist has discovered a drug that blocks phosphoglucoisomerase, an enzyme that catalyzes the second reaction in glycolysis. He wants to use the drug to kill bacteria in people with infections. However, he cannot do this because _____. ( Concept 9.2 ) 11. In glycolysis, there is no production of carbon dioxide as a product of the pathway.
