Which of the following statements regarding the events in the functioning of photosystem II is FALSE?
Light energy excites electrons in an antenna pigment in a photosynthetic unit
The excitation is passed along to a molecule of P680 chlorophyll in the photosynthetic unit
The P680 chlorophyll donates a pair of protons to NADPH, which is thus converted to NADP+
The electron vacancies in P680 are filled by electrons derived from water
The splitting of water yields molecular oxygen as a by-product
