Question

Which photosystem is associated with the splitting of water?

Answer 1

Splitting of Water

1. Water splitting is a chemical reaction that produces hydrogen and oxygen as byproducts.
2. Through technological breakdown, efficient and cost-effective water splitting can be achieved, which could support a hydrogen economy.
3. The electrons that were transferred from photosystem $\mathrm{II}$ must be replaced. It can be done with the electrons that are present as a result of water splitting.
4. Photosystem $\mathrm{II}$ is connected with water splitting, in which the water molecule separates into hydrogen ions, oxygen atoms, and an electron. As a result, the net outcome of photosynthesis is oxygen.
5. This electron must be replaced by those provided by photosystem $\mathrm{II}$, which come from photosystem $\mathrm{I}$.
6. $2{\mathrm{H}}_2\mathrm{O}\to 4{\mathrm{H}}^{+}+{\mathrm{O}}_2+4{\mathrm{e}}^{-}$.
7. The Photosystem $\mathrm{II}$, which is physically placed on the inner side of the thylakoid membrane, is associated to the water splitting complex.
