Question

How does PS II supply electrons continuously?

Answer 1

PS II supplies electrons

1. The initial protein complex in the light-dependent processes of oxygenic photosynthesis is called photosystem II.
2. In higher plants, algae, and cyanobacteria, the photosynthetic initial reaction is carried out by Photosystem II (PS II).
3. PS II continuously provides electrons by splitting water molecules.
4. The water-splitting complex is associated with PS II on the thylakoid's inner membrane.
5. The water-splitting leads to the synthesis of oxygen, protons, and electrons.

Reaction: $2{\mathrm{H}}_2\mathrm{O}\to 4{\mathrm{H}}^{+}+{\mathrm{O}}_2+4{\mathrm{e}}^{-}$
