Research Abstract

To elucidate the energetics for the light-induced charge separation in photosynthetic bacteria, in which redox properties of cofactors were obscure because of insufficient measurement technique, redox potentials of the cofactors have been determined in the present work by spectroelectrochemistry using an optically-transparent thin-layer electrode cell. Further, by investigating the cofactors' redox potentials in various species, we have discussed the inevitability and admissibility of the energetics in the photosynthetic reactions.
