  2. 3. NADP 2H+ ADP ATP PSII PSI X Y Solar energy Light Reaction NADPH 2 Solar energy H 2 O O 2 Solarenergy is converted to chemical energy ia ATP & NADPH 2. T hey are used in the Dark reaction a ADP W.B.K.Hettiarachchi
  3. 4. 2H+ ADP ATP PSII PSI X Y Light Reaction NADPH 2 H 2 O O 2 PHOTOLYSIS of WATER Exited electrons are released from PSII Picked up by low enrgy electron accepter Photophosphorylationh Electrons are accepted by the light energy absorbed by PS I Exited electrons are released from PSI Picked up by low enrgy electron accepter Electrons are activated by PS 11 Electrons produced in the photolysis of water are gained by PS II Electrons are accepted by NADP to produced NADPH 2 Soloar Energy is absorbed by PS II 2H+ O 2 ADP Passed along a sequence of low energy electron carriers Soloar Energy is absorbed by PS I
  4. 5. NADP 2H+ ADP ATP PSII PSI X Y LIGHT REACTION NADPH 2 H 2 O O 2 PHOTOLYSIS of WATER Exited electrons are released from PS II picked up by a low energy electron accepter Passed along a series of electron accepters Electrons are activated by PS I Exited electrons are released Picked up by a low energy electron accepter Electrons are activated by PS II Electrons released from photolysis of water are accepted by PS II Electrons are accepeted to NADP + to form NADPH 2 Solar energy is absorbed by PS II O 2 Solar energy absorbed by PS I 1 2 3 4 5 5 6 8 7 9 9 10 11 12 PHOTOPHOSPHORYLATION
  5. 6. NADP 2H+ ADP ATP PSII PSI X Y LIGHT REACTION NADPH 2 Light energy H 2 O O 2 a ADP Light energy
  6. 7. After Using it, Please send me your feedback. My e-mail [email_address] I can e-mail this, if you can’t download.  W.B.K. HETTIARACHCHI 1/1 &quot;DUMINDU &quot; Wigoda Bemmulla (11040) SRI LANKA
