| Research Abstract |
In photosynthesis of higher plants and algae, light energy is efficiently collected and transferred by pigments embedded in the protein. The light energy induces the electron and the proton transfers which promote the water-splitting and the oxygen-evolving reaction. To clarify the mechanism of such a reaction, we need to use not only experimental but also theoretical approaches. In this study, we constructed a theory that well describes experimental results, and explained a part of mechanisms of the energy, the electron and the proton transfers in the photosynthetic protein.
