WebApr 10, 2024 · The electrons transfer from pheophytin to plastoquinone, which takes the 2 electrons from Pheophytin, and two hydrogen Ions from the stroma and forms PQH 2, which later is broken into PQ, the 2 electrons are released to Cytochrome b6f complex and the two hydrogen ions are left out into thylakoid lumen. The electrons then travel through the … WebThe cytochrome b6f complex is often drawn as pumping protons, but then someone told me that actually there is no pumping, rather the Q cycle. According to this view, what actually moves the protons is that a PQ takes up 2 H + from the stroma as it is reduced and another two PQ release 2H + into the lumen as they reduce PC and partially reduce ...
