2. Describe how oxygen gas (O₂) 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 CO2, 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 (CO₂) 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?
