obsolete primary charge separation in photosystem II (obsolete GO:0009771)
OBSOLETE. Energized reaction-center P680 chlorophylls on photosystem II donate an electron to a loosely bound acceptor molecule, the quinone Q, on the stromal surface of the thylakoid membrane. The result is charge separation; a negative charge on the stromal side of the thylakoid membrane and a positive charge on the luminal side.
