4.1.1 Photosynthetic Reaction

• photosynthesis = 6CO2 + 6H2O → C6H12O6 + 6O2
• photosynthesis = carbon dioxide + water (+ light energy) → glucose + oxygen
• What is CO2?

  Carbon dioxide.
• What is H2O?

  Water.
• What is O2?

  Oxygen.
• What is C6H12O6?

  Glucose.
• What is the chemical form of oxygen?

  O2.
• What is the chemical form of carbon dioxide?

  CO2.
• What is the chemical form of glucose?

  C6H12O6.
• What is the chemical form of water?

  H2O.
• Is photosynthesis an endothermic or exothermic reaction?

  Endothermic.
• Where does photosynthesis take place?

  Chloroplasts.
• Why is photosynthesis an endothermic reaction?


  Energy is transferred from the environment to the chloroplasts by light.
