Photosystem Overview & Characteristics What is a Photosystem?

WebThe various accessory pigments absorb light of different wavelengths and pass the energy down the photosystem. Eventually the energy reaches the primary pigment that acts as a reaction centre. There are 2 types of photosystem: Photosystem One - PS I: Its primary pigment is a molecule of chlorophyll a with an absorption peak at 700nm. It is ... WebThe Light-Dependent Reaction. Light energy is used to breakdown water in a reaction known as photolysis; this produces hydrogen ions, electrons, and oxygen in the thylakoid lumen. A proton gradient is formed as the photolysis of water results in a high concentration of hydrogen ions in the thylakoid lumen.
