5.2 Photosynthesis
Light Dependent Reactions
Plants use PS 1 and PS 2 to produce ATP and NADH
This is a 2-part process called non-cyclic phosphorylation
Non-Cyclic Phosphorylation
Photo-system II
light energy hits P680 and excites an electron of reaction center chlorophyll a
the e- is captured by primary electron accept-or which initiates ETC
the e- lost by the chlorophyll a molecule in P680 are replenished by coupling the photooxidation of chlorophyll a to the photolysis of water
a water-splitting complex in the thylakoid lumen splits water into oxygen, hydrogen ions (protons, H+), and electrons
the oxygen is released into the atmosphere as a waste product. The electrons are used to replace the es lost by the P680 chlorophyll a
