In Pathway: photosynthesis light reactions , hydrogen production VIII

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Mass balance status: Balanced.

Enzyme Commission Primary Name: photosystem II

Enzyme Commission Summary:
Contains chlorophyll a, β-carotene, pheophytin, plastoquinone, a Mn4Ca cluster, heme and non-heme iron. Four successive photoreactions, resulting in a storage of four positive charges, are required to oxidize two water molecules to one oxygen molecule.
