Non-cyclic photophosphorylation

• Light energy is used for two processes: Phosphorylation of ADP to produce ATP (ADP + Pi -> ATP) and photolysis

  A) Granal Lamellae

  B) Intergranal Lamella

  C) light

  D) electrons

  E) hydrogen ions

  F) Electron Carriers

  G) photolysis

  
• Photolysis: Absorbs light energy, replacing electrons lost from p680; PSII enzyme catalyses reaction: 2H_2O → 4H^+ (combine with e^- reducing NADP and helping chemiosmosis make ATP) + O_2 (released as waste product) + 4e^-
