Diagram 9 CALVIN CYCLE: Phase 2-Reduction Diagram 10 30-3 SAP Student Worksheet CALVIN CYCLE: Phase 3-Regeneration PART 7: BIOSYNTHESIS 1. Complete the following sentence based on Diagram 11. Glyceraldehyde-3-phosphate (G3P) can be used by plant cells to make and 2. Which molecule in Diagram 11 is used to transport energy to other parts of the plant? 3. Which molecule in Diagram 11 is stored in the plant for later use as an energy source? GATP HAPPY P7 AP CHAP 2. At the end of the Calvin cycle, what molecules have the energy that originally came from light? SAIP -SAD SHOP EF Diagram 11 Organic molecules G3P Glyceraldehyde-3-phosphate Sucrose Starch hhmi Biolnteractive Photosynthesis PART 8: TEST YOUR KNOWLEDGE 1. Based on everything you've learned from the animations, what is the overall purpose of photosynthesis? Animations Student Worksheet 2. Describe how oxygen gas (O) is produced during photosynthesis. Include the specific structures in the plant where the reaction occurs. 3. Describe the path of an electron from a molecule of water to the sugar G3P. 4. Describe how ATP is produced in the light reactions. 5. Which of the following statements best explains how the energy in a photon of light is stored in a molecule of the sugar G3P? a. Light energy directly provides energy to RuBP and CO, which produce G3P in the Calvin cycle. b. Light energy directly provides energy to ATP synthase, which produces ATP during the light reactions. c. Light energy energizes electrons to make ATP and NADPH, which provide energy to produce G3P in the Calvin cycle. 6. When three molecules of carbon dioxide (CO) react with three molecules of RuBP during the Calvin cycle, six molecules of the sugar G3P are produced. One G3P molecule exits the Calvin cycle during Phase 2. What happens to the other five G3P molecules?
