The majority of ATP in aerobic respiration is produced in: Calvin Cycle Glycolysis Electron Transport Chain Krebs Cycle 2 / 14 2. Glycolysis results in the net production of which of the following per glucose molecule? 4 ATP, 2 NADH 2 ATP, 2 NADH 4 ATP, 4 NADH 2 ATP, 4 NADH 3 / 14 3. Which molecule is a product of non-cyclic photophosphorylation in photosynthesis? ADP Carbon dioxide Oxygen NADP+ 4 / 14 4. Where does glycolysis occur within the cell? Mitochondria Nucleus Cytoplasm Chloroplast 5 / 14 5. Which of the following statements is correct about light-dependent and light-independent reactions? Light-dependent reactions produce glucose. Light-dependent reactions fix CO2. Both occur in the stroma. Light-independent reactions require ATP and NADPH. 6 / 14 6. Which of the following best describes the Calvin Cycle? It occurs in the thylakoid membrane. It is dependent on light energy. It synthesizes glucose from CO2 and H2O. It produces oxygen as a byproduct. 7 / 14 7. Which of the following is a final electron acceptor in anaerobic respiration? Sulfate Oxygen NAD+ Water 8 / 14 8. During oxidative phosphorylation, ATP is generated through the process known as: Substrate-level phosphorylation Chemiosmosis Fermentation Photophosphorylation 9 / 14 9. Which of the following is true about the role of light in photosynthesis? It is required in the Calvin cycle. It directly synthesizes glucose. It provides energy to split water molecules It fixes carbon dioxide into organic molecules. 10 / 14 10. Photosystem II differs from Photosystem I in that: Photosystem I generates oxygen. Photosystem I is involved in the Calvin cycle. Photosystem II uses water as an electron donor. Photosystem II operates only in the dark. 11 / 14 11. Which of the following distinguishes anaerobic from aerobic respiration? Both produce equal amounts of ATP. Anaerobic respiration requires oxygen. Anaerobic respiration does not involve the Krebs cycle. Aerobic respiration produces lactic acid. 12 / 14 12. Which of the following statements is true about the overall process of photosynthesis? It converts chemical energy into light energy. It stores energy in the form of glucose. It only occurs in the presence of oxygen. It releases CO2 and consumes oxygen. 13 / 14 13. Which factor is least likely to affect the rate of photosynthesis? Light intensity Temperature Carbon dioxide concentration Oxygen concentration 14 / 14 14. What is the primary purpose of the light-dependent reactions of photosynthesis? To generate ATP and NADPH To convert CO2 into oxygen To produce glucose To fix carbon into a stable form Your score isThe average score is 51% LinkedIn Facebook VKontakte 0% Restart quiz Anonymous feedback See review Send feedback Show 102550100 entriesSearch: User NameDurationScoreHaya3 minutes 56 seconds57%Muskan2 minutes 20 seconds78%Muskan5 minutes 37 seconds42%Sajid khan36 seconds28%Showing 1 to 4 of 4 entriesPrevious1Next
