Name: __________________________________________________________ Date: ______________________ Cellular Respiration/Photosynthesis Review ____________________ Period: The following statements listed below refer to the events that occur in either the light reactions or light – independent reactions (Calvin Cycle, Dark Reactions) of photosynthesis. Use the following key to show which events occur in which phase of photosynthesis. A = Light Reactions B= Light Independent Reactions 1. _________ Oxygen is produced. 2. _________ CO2 becomes part of a glucose molecule. 3. _________ ATP is used. 4. _________ NADPH is produced (NADP 5. _________ Are sometimes called the dark reactions. 6. _________ Occurs in the thylakoid membrane. 7 _________ Chlorophyll captures light energy. 8. _________ ATP is produced. 9. _________ NADPH is used (NADPH 10. _________ Produces a 3 carbon sugar. 11. _________ An electron transport chain is involved. 12. _________ Carbohydrates are produced. 13. _________ Electrons are boosted to higher energy levels. 14. _________ Water is split. 15. _________ Occurs in the stroma. 16. _________ Accessory pigments help to carry light energy. 17. _________ Uses the enzyme Rubisco. 18. _________ Can occur in the light or dark. 19. _________ Red and blue wavelengths of light are absorbed. NADPH). NADP). Use the above diagram to answer this question and the next 11 questions: Identify the substances represented by the arrows.

E. 7 Statement Type of Process Fermentation Aerobic Lactic Acid Alcoholic Respiration 1. It requires oxygen. 2. It does not require oxygen. 3. It requires energy input from 2 ATP. 4. It can produce a net of 38 ATP. 5. It can produce a net of 2 ATP. 6. It is important in baking and brewing. 7. It causes the pain of muscle fatigue. Statement 1. Occurs in the cytoplasm. 2. Occurs in mitochondrial matrix. 3. Occurs the on the inner mitochondrial membrane. 4. Requires ATP 5. Produces ATP 6. Requires NADH or FADH2 7. Produces NADH or FADH2 8. Requires oxygen. 9. Requires water. 10. Produces water. 11. Produces CO2. 12. Part of aerobic cellular respiration. In the following chart: Gylcolysis Krebs Cycle ETC For each NADH produced the stages of respiration, 3 ATP’s are produced in the ETC. For each FADH2 produced in the stages of respiration, 2 ATP’s are produced in the ETC.
