Answer #1

OPTION A: WATER. The role of water in photosynthesis is supply electrons to these redox reactions, the water acts as a source of electrons. water molecule is a very weak reducing agent, the electrons must be energized by photons of sunlight, so that acquire sufficient potential to reduce inorganic molecules carbon, nitrogen and sulfur. Energization of electrons from water is done by chlorophyll, the green pigment typical plant world that acts as a receiver and converter of solar energy into chemical energy.
