  1. The system will be returned to the state that existed before the light excitation, and all the absorbed energy will be converted into heat
  2. The system will be returned to the state that existed before the light excitation, because there is no way to  returned  back to the reaction centre
  3. The system will be returned to the state that existed before the light excitation, and all the absorbed energy will be converted into emission of light
  4. System will be returned to the state that existed before the light excitation, and all the absorbed energy will be converted into re-emitting energy as a photon
