Light-Dependent reactions Function: Produces NADPH and ATP required by the second set of reactions ( Light-Independent ) to build sugar Light energy (photon) excites electrons Excited (high energy) electrons are then transferred from one intermediate to another Electron transfer is used to generate NADPH as well as ATP

Carbon fixation CO2 CO2 CO2 +RuBP + RuBP +RuBP 6 C + 6C + 6C =18 Carbons-15 RuBP regeneration 3C excess = 1 G3P molecule 2 G3P = 6 C = Glucose => 6 CO2---> 1 Glucose CO 2 Photorespiration Rubisco has affinity for oxygen as well Rubisco + O 2 G3P (no carbon source) C4 and CAM plants have adaptations to overcome this Photorespiration C4 plants Move Calvin Cycle into bundle sheath cells What do CAM plants do? What is the relationship between the Calvin Cycle and the Citric Acid Cycle?
