Chapter 10: Redux 6CO2 + 6H2O + light energy C6H12O6 + 6O2 Oxygen given off by plants is derived from H2O and not CO2 Reverses direction of electron flow: water is split, and electrons are transferred along with hydrogen ions from water to carbon dioxide, reducing it to sugar. Endergonic because electrons increase in potential energy Photophosphorylation - light reactions generate ATP using chemiosmosis to power the addition of P to ADP Carbon fixation: the incorporation of CO2 from the air into organic molecules o Fixed carbon is reduced to a carbohydrate by the addition of electrons Light- electromagnetic energy Carotenoids- absorb violet and blue green light, appear as yellow and orange. Used for photoprotection because they absorb and dissipate excessive light energy that would otherwise damage chlorophyll Accessory pigments with different absorption spectra are photosynthetically important Linear Electron Flow - flow of electrons through the photosystems and other molecular
