Question

During non-cyclic photophosphorylation, electrons are continuously lost from the reaction centre of PS II. Which source is used to replace these electrons?\

Professor PC Thomas Classes · Answer

(c) : The electrons that were moved from photosystem II must be replaced. This is achieved by the electrons available due to the splitting of water. The splitting of water is associated with the PS II. Water split into $\mathrm{H}^{+},[\mathrm{O}]$ and electrons. This creates oxygen one of the net products of photosynthesis. The electrons needed to replace those removed from photosystem I are provided by photosystem II.\
