When chlorophyll molecules are struck by the sunlight they release 2 electrons that flow into the electron transport chain. to keep the process of photosynthesis running the chlorophyll molecules find replacement electrons. what is the source of these replacement

Answer; splitting of water

Explanation:the first photo system gets excited when it absorbs a photon of light from the sun,it looses electron

.this electron definiency is replaced by the splitting of water through light energy and the splitting resulting in the release of electrons and hydrogen ion,which is involved in the production of ATP

is this a psat question, if so do not cheat try your best.

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics
