Schematic model of the major protein complexes involved in photosynthesis

Figure 1 is a schematic model of the main photosynthetic complexes engaged in oxygenic photosynthesis situated within the higher plant / green algal thylakoid membrane, where PSII is shown as the first major complex in the electron transport chain, after light (hv) has been absorbed by its light-harvesting components, the Lhcb proteins.
