Quiz Section 4.4 Cellular Respiration 1 1. What is the Principle function of cellular respiration? A. It produces oxygen so we can breathe. B. It produces ATP for cellular activity. C. It breaks down carbohydrates to form glucose. D. It creates hydrogen ions from water molecules. 2 2. If a process is aerobic, it means that. . . A. B. C. D. The process requires oxygen to work. The process requires carbon dioxide to work. Glucose is required to fuel the process. It is dependent on ATP. 3 3. Glycolysis is what type of process? A. B. C. D. Aerobic Reducing Oxidizing Anaerobic 4 4. How are glycolysis and cellular respiration connected? A. Cellular respiration provides the glucose glycolysis needs to take place. B. Glycolysis’s primary function is to provide ADP to the Krebs cycle. C. The mitochondria utilize the products of glycolysis to power cellular respiration D. Glycolysis produces the carbon dioxide the mitochondria need for cellular respiration. 5 5. What are the reactants in cellular respiration? A. One 6 carbon molecule from glycolysis and carbon dioxide. B. Three-carbon molecules from glycolysis and oxygen. C. Three-carbon molecules from glycolysis and carbon dioxide. D. One 6 carbon molecule from glycolysis and oxygen. 6 6. What are the products of cellular respiration? A. B. C. D. Water and carbon dioxide. Water and oxygen Water and hydrogen ions Carbon dioxide and oxygen 7 7. Where does the Krebs cycle take place? A. B. C. D. In the cell’s cytoplasm In the Golgi apparatus In the matrix of the mitochondrion In the chloroplast 8 8. What are the primary products of the Krebs cycle? A. Glucose and ATP B. Energy carrying molecules and carbon dioxide. C. Oxygen and ADP for the electron transport chain. D. ATP and ADP 9 9. What is transferred from the Krebs cycle to the electron transport chain? A. B. C. D. Water and ADP ADP and oxygen High energy molecules to make ATP ATP to make high energy molecules 10 10. What are the primary products of the electron transport chain? A. B. C. D. ATP and water Lots of ADP and water ATP and carbon dioxide ADP and oxygen 11 11.
