If I understand it correctly:
The Q cycle starts with PQH2 it removes the 2H(+) and gives one electron to Plastocyanin and the other to a stored Plastoquinone to charge it to Plastoquinone (-). This process is repeated and adds the electron to the stored Plastoquinone(-) to create a Plastoquinone (-2). This then gets 2H(+) to form PQH2. And the cycle begins anew.
But in a lot of pictures is shown that the excited P680 gives the electron to Pheophytin and that gives it to the Q cycle.
Please let me know when and where the Pheophytin interacts to give the electron.
