What electrons are in photosynthesis?
Ultimately, the electrons taken when water is split in
photosystem II during the process of photolysis.
Photosystems loose electrons during light reactions.Their lost electrons are replaced by photolysis of water
If you are referring to the "Plant Pigments and Photosynthesis" Lab Then, the DPIP is used to substitute NADP+. In photosynthesis, electrons are normally transferred to NADP+. However, DPIP will take its place in this experiment. DPIP is normally blue. When it is reduced, or gains electrons, it will turn colorless. DPIP is used to show that photosynthesis is taking place.
§Photosynthesis, like respiration, is a redox (oxidation-reduction) process -Water molecules are split apart by oxidation, which means that they lose electrons along with hydrogen ions (H+) -Then CO2 is reduced to sugar as electrons and hydrogen ions are added to it This means that the electrons are moved from a water molecule to a carbon dioxide molecule. H2O >> CO2
