Photosynthesis & Cell Respiration: Cells and Energy

Practice Chapter Test Answer Key Multiple Choice 1. b 2. a 3. a 4. d 5. a 6. c 7. b 8. c 9. b 10.a 11.d 12.c 13.d 14.b 15.a Short Answer 16.Photosynthesis 17.energy from sunlight 18.Accept either NADPH or ATP. 19.The electron transport chain is located in the membrane of the thylakoids. The main function of the thylakoids is to absorb energy from sunlight and transfer it to the second stage of photosynthesis (the lightindependent reactions).

20.The circle represents the Calvin cycle. The carbon dioxide comes from the atmosphere. 21.Fermentation and Cellular Respiration 22.Accept any answer that includes ATP, NADH, or FADH2. 23.The sugar comes from the food we eat. 24.The Krebs cycle. For products, accept any two: carbon dioxide, NADH, FADH2, ATP. 25. During strenuous exercise, there is not enough oxygen present in the cells to pick up electrons at the end of the cellular respiration process. Instead, fermentation produces a steady supply of NAD+ so that glycolysis can continue to produce a small amount of ATP.
