Metabolism – Photosynthesis & Cellular Respiration

Name:__________________________ Per:_________ Biology Unit 4: Metabolism – Photosynthesis & Cellular Respiration Study Guide Photosynthesis 1. Write the overall chemical equation for photosynthesis (label the reactants & the products). 2. What is the role of the following items in photosynthesis: a. Chloroplast: b. Thylakoid membrane: c. Pigments (chlorophyll a, chlorophyll b, cartenoids: 3. Label the diagram on the right with the following terms: a. b. c. d. e. f. g. h. i. Calvin Cycle ATP NADPH Light Light Reaction 02 H20 CO2 PGAL (Sugar) 4. Complete the following chart that summarizes the 2 steps of photosynthesis: Reaction Location Reactants Light Reaction Products Calvin Cycle (Dark Rxn) 5. In Photosynthesis, what is water used for? What is CO2 used for? 6. What is PGAL? How does this relate to Glucose? 7. Why is the dark reaction described as a “Cycle”? How many CO2’s are required to make 1 PGAL? How many CO2’s are required for one glucose molecule? Cellular Respiration 8. Write the overall equation for Cellular Respiration (label the reactants and the products). 9. What is the purpose for cellular respiration in cells? What types of organism perform cellular respiration? 10. What does ATP stand for? Why is it so important for all living things? 11. Explain the differences between aerobic and anaerobic respiration by filling out the chart below: Location of Process Is Oxygen Used? in Cell Amount of ATP produced? Organisms that do this process Anaerobic Respiration Aerobic Respiration 12. What happens after Glycolysis if oxygen is not present? Does this help make more ATP? 13. Why does Lactic Acid Fermentation occur in your muscle cells? What type of fermentation occurs when making bread? Why? 14. Why are anaerobic organisms usually always small and single-celled? Explain. 15. Do plants perform cellular respiration? Why or why not? 16. Using your knowledge of cellular respiration, why does your heart rate and breathing rate increase during physical activity? Why do your muscles sometime burn when working out? 3. 17. Label the diagram on the right with the letters of the following terms: a. Glucose b. Oxygen c. 38 ATP d. Carbon dioxide e. Water f. Glycolysis g. Krebs Cycle/Citric acid cycle h. Electron transport i. Mitochondria 1. 4. 5. 2. 7. 18. Complete the following chart that summarizes the 3 steps of aerobic respiration: Name of Stage Location in cell 6. 9. Oxygen Required? # of ATP Produced Glycolysis Krebs Cycle (Citric Acid Cycle) Electron Transport 19. In Respiration, what is O2 used for? How is water produced? Why is CO2 released? 20. Why are plants considered “Producers or Autotrophs” and animals are “Consumers or Heterotrophs”? 8.
