WebPhotosystem II. Photosystem II (PSII) is a specialized protein complex that uses light energy to drive the transfer of electrons from water to plastoquinone, resulting in the production of oxygen and the release of reduced plastoquinone into the photosynthetic membrane. The key components of the PSII complex include a peripheral antenna system ... WebApr 10, 2024 · Being a light reaction, non-cyclic photophosphorylation happens in the thylakoid membrane. Where first, a water molecule is broken down into 2H + + ½ O 2 + 2e-by a procedure called photolysis (light-splitting). Then the two electrons from the water molecule are preserved in photosystem II, while the 2H + and ½ O 2 are released

Light energy is transferred to the reaction center; Antenna pigments capture a photon of light; Two electrons carrying potential energy are passed to the electron transport chain.
WebThe phycobilisome (PBS) is an antenna protein complex in cyanobacteria, Glaucocystophytes, and red algae. In the standard PBS, the rod-core PBS, the rods are connected to the core by the rod-core linker protein CpcG. The rod-core PBS transfers the light energy mainly to photosystem (PS) II and to a lesser extent to PSI.
