Light Reaction in Photosynthesis : 

W.B.K.Hettiarachchi Light Reaction in Photosynthesis The following slides show five forms of presentation of thez light reaction You can choose a suitable one and include it in your PPT ’ After Using it, Please send me your feedback. My e-mail karuhetti@yahoo.com I can e-mail this, if you can’t download it. Thank you.

Slide 2:

Slide 3: 

W.B.K.Hettiarachchi NADP 2H+ ADP ATP PSII PSI X Y Solar energy Light Reaction NADPH2 Solar energy H2O O2 Solarenergy is converted to chemical energy ia ATP & NADPH2.T hey are used in the Dark reaction a ADP W.B.K.Hettiarachchi

Slide 4: 

W.B.K.Hettiarachchi 2H+ ADP ATP PSII PSI X Y Light Reaction NADPH2 H2O O2 PHOTOLYSIS of WATER Exited electrons are released from PSII Picked up by low enrgy electron accepter Photophosphorylationh Electrons are activated 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 NADPH2 Soloar Energy is absorbed by PS II 2H+ O2 ADP Passed along a sequence of low energy electron carriers Soloar Energy is absorbed by PS I

Slide 5: 

W.B.K.Hettiarachchi NADP 2H+ ADP ATP PSII PSI X Y LIGHT REACTION NADPH2 H2O O2 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 NADPH2 Solar energy is absorbed by PS II O2 Solar energy absorbed by PS I 1 2 3 4 5 5 6 8 7 9 9 10 11 12 PHOTOPHOSPHORYLATION
