Biology a level question - photosynthesis

can anyone explain to me visually why 2 electrons are needed to be released from the light dependent stage?
I understand that the photolysis of water releases 2 electrons but visually I cannot see where these 2 electrons fit in the model?
thanks

I don't really understand how energy is released in photoionisation of chlorophyll as well?

the electrons are released so that they can be transferred to the electron acceptor so that the reduction of NADPH can happen

radiation energy is able to excite the electrons in the chlorophyll molecule and excite them to a higher energy level, which is where the electrons come from. This is also where the energy from photoionisation comes from
