During non-cyclic photophosphorylation, which molecule acts as the ultimate source of electrons to replace those lost by Photosystem II?
Show answer and explanation
Correct answer: Water
Water undergoes photolysis (splitting) associated with the PS II complex on the inner side of the thylakoid membrane. This process releases electrons, protons, and oxygen, ensuring a continuous supply of electrons to PS II.
