sunlight to excite the electrons
Water participates directly in the light reactions of photosynthesis by donating electrons to photosystem II. Photosystem I and photosystem II both contain chlorophyll as molecules.
Excite electrons
When the light "activates" the electrons, it kicks them up into higher orbitals where they have more energy. That extra energy is utilized to power the photosynthesis reaction.
No it does not. Respiration gets its energy from ATP(produced in photosynthesis when electrons travel through the electron transport chain)
Electrons are used as an exchange currency during photosynthesis. The energy that provides the boost for these electrons comes from the electron transport chain.
sunlight to excite the electrons
Photosynthesis is not a system. It is a process in plants. It is very important process.Photosynthesis is a process of making sugars from CO2 and water by using light energy. Photosystem I and photosystem II are involved in this process to transfer electrons across the membrane. Photosynthesis occurs in plants algae and certain bacteria.
The thylakoid membrane contains 2 photosytems, known as Photosystem I and Photosystem II. Together, they function to absorb light and transfer energy to electrons.
From energy in photons
Water participates directly in the light reactions of photosynthesis by donating electrons to photosystem II. Photosystem I and photosystem II both contain chlorophyll as molecules.
This pigment is chlorophyll. It is struck by photons of light which excites it's electrons into a higher energy level where they enter photosystem II.
The flow of electrons in photosynthesis has four sequential steps. Here is the sequence: from water to photosystem II then photosystem I and lastly NADP.

it is something to do with electrons and being charged!
