Photosynthesis

Light dependent reaction

• Light energy is absorbed by chlorophyll. Electrons in chlorophyll are excited (raised to a higher energy level)
• Electrons are lost from the chlorphyll molecule (and are transferred to electron carriers in the thylakoid membrane)
• Electrons are passed between carriers in the ETC
• Energy released during the transfer of the electrons along the ETC is used to synthesise ATP
• H2O in the thylakoids split into electrons, H+ and O2, using energy from the sunlight 'photolysis'
• The electrons from…
