photosystem I and II are reaction centers that capture light energy in order to drive oxygenic photosynthesis. They can only do so by interacting with multisubunit cytochrome b6f complex. This complex receives electrons from photosystem II and passes them to phosptosystem I, pumping protons across the membrane and powering the Q-cycle. Cytochrome b6f can switch to a cyclic mode of electron transfer around photosystem I using an unknown pathway |

a pathway of cytochrome c biogenesis is involved in the assembly of the cytochrome b6f complex in Arabidopsis chloroplasts |
