    From what I already know, photosystem II excites electrons and then these electrons lose this energy by passing down a series of redox reactions - the electron transport chain.

    Though, are these electrons naturally free within PSII or are they provided by the water splitting complex?

    Thanks.

    Photolysis replaces the electrons lost in PSII. A porphyrin group in PSII contains a magnesium atom which becomes exited and releases two electrons, which in turn pass down the electron transport chain.
