Photosynthesis Animation Photochemical Reaction Youtube This educational video is created for middle school students. the most important photochemical reaction is photosynthesis, a process that converts light ener. 6. the light reactions light reactions are the steps in photosynthesis that occur on the thylakoid membranes of the chloroplast and that convert solar energy to the chemical energy of atp and nadph, evolving oxygen in the process. the key components of the light reactions of photosynthesis are the two photosystems, two electron transport chains. The net reaction of all light dependent reactions in oxygenic photosynthesis is: 2h 2 o 2nadp 3adp 3pi → o 2 2nadph 3atp key points light energy splits water and extracts electrons in photosystem ii (psii); then electrons are moved from psii to cytochrome b6f to photosystem i (psi) and reduce in energy. Figure 8.16 a photosystem consists of 1) a light harvesting complex and 2) a reaction center. pigments in the light harvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. the light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. the excited electron.
