The structure of the four major protein complexes in the thylakoid membrane are organised form such as ;

a.) PSII is located predominantly in the stacked regions of the thylakoid membrane and Cytochrome b6f complexes are evenly distributed

b.) PSI and ATP synthase are found in the unstacked regions protruding into the stroma

c.) Lateral separation of the two photosystems requires that electrons and protons produced by PSII be transported directly to PSI and the ATP coupling enzyme

d.) Four main protein complexes of the thylakoid membrane, shown also are the two diffusible electron carriers—plastocyanin, which is located in the thylakoid lumen, and plastohydroquinone (PQH2) in the membrane, The lumen has a positive electrical charge with respect to the stroma
