Light Phase

    Cards (5)

    • The light phase takes place in the grana of chloroplasts
    • Radiant energy from the sun is absorbed by chlorophyll molecules in the thylakoids
    • Energy transformation takes place and radiant energy is transformed into chemical energy
    • Chemical energy is used for two processes
      Photolysis:
      Water molecules are split into Hydrogen atoms (transferred to dark phase) and oxygen atoms (released into atmosphere as a gas)
    • The energy carrier ATP is formed and it is used again in the dark phase
