Functional Modeling of Electron Transfer in Photosynthetic Reaction Centers

  • Vladimir Shinkarev
Part of the Advances in Photosynthesis and Respiration book series (AIPH, volume 24)


In recent years significant progress has been made in gaining insight into the structure and function of the reaction centers (RCs) of plants, algae, and photosynthetic bacteria. All RCs with known structures have a porphyrin–quinone core. This core is coupled with specific donors, acceptors, and light-harvesting antenna. RCs can use both watersoluble and lipid-soluble donors and acceptors. The electron exchange of RCs with these donors and acceptors occurs via specialized processing sites, which are responsible for recognition of respective donor-acceptor, and for channeling the electrons and protons in and out of the complex. The purpose of this chapter is to describe some simple kinetic models of flash-induced electron transfer in these RCs. In our consideration we try to find the balance between analytical solutions for the simplest models and numerical calculations for a detailed quantitative description of electron transfer in RCs.
