OEC:

Organization Executive Course.

The oxygen evolving complex is a water oxidizing enzyme involved in the photooxidation of water during the light reactions of photosynthesis. The complex can exist in 5 states: S0 to S4. Photons trapped by photosystem II move the system from state S0 to S4. S4 is unstable and reacts with water to produce oxygen.
