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 |

under white-light illumination and aerobic conditions, chlorophyll a bound in the intact Cyt b6f can be bleached by light-induced singlet oxygen. Under similar experimental conditions, singlet oxygen is also detected in the Rieske-depleted Cyt b6f complex, but not in the isolated Rieske FeS protein |
