Electron Transfer in Photosynthesis

Abstract

In the primary process of the light reactions in photosynthesis, an excited chlorophyll releases an election, followed by sequential charge shifts with high efficiency. Prosthetic groups such as chlorophylls and quinones bind at the reaction center polypeptides. The protein regulates the energy levels and dielectric responses of the prosthetic groups. How the functions of the reaction center protein has been evolved to carry out the best performance in the electron transfer will be discussed.
