Photosynthesis 0.0 / 5 ? BiologyHuman, animal and plant physiologyA2/A-levelAQA Created by: romy kaleCreated on: 03-10-13 19:55 ATP: Why is it useful releases energy in small amounts broken down in one step process makes energy available rapidly phosphorylates can be reformed/made again (recycled) 1 of 5 Light dependent reaction Light excites/ raises energy level of electrons in chlorophyll chlorophyll emitts excited electron electrons pass down electron transport chain (electrons) reduce carriers/ passage involves redox Energy released ATP generated from ADP and Pi photolysis of water provides the electron to recharge chlorophyll molecule h+ ions then reduce NADP using the electron from end of electron transport chain 2 of 5 Light Independent reaction Carbon dioxide combines with ribulose biphosphate/ RuBP To produce two molecules of GP Reduced to TP which requires reduced NADP and energy from ATP 3 of 5 If you remove the light from calvin cycle... If ATP and NADP removed no energy to turn GP to TP so no carbs produced from TP + so no respiration 4 of 5 Why is it important for plants to respire and phot In the dark no ATP produced in photosynthesis Some tissues unable to produce ATP ATP cant move from cell to cell plant uses more ATP than is produced in photosythesis ATP required for active trasport ATP used for synthesis of amino acids 5 of 5
