Abstract
The exciton transfer between light-harvesting complex 1(LH1) and photosynthetic reaction center dimer is investigated theoretically. We assume a ring shape structure of the LH1 complex with dimer in the ring centre. The kinetic equations which describe the energy transfer between the antenna complex and reaction center dimer were derived. It was shown that the dimer does not act as a photon trap. There is a weak localization of the exciton on the dimer and there is relatively rapid back exciton transfer from dimer to antenna complex which depends on the number of the pigment molecules in the antenna ring. The relation between the rates of the exciton transfer from the antenna complex to dimer and back transfer from dimer to antenna complex has been derived.
期刊介绍：
Many physicists are turning their attention to domains that were not traditionally part of physics and are applying the sophisticated tools of theoretical, computational and experimental physics to investigate biological processes, systems and materials.
The Journal of Biological Physics provides a medium where this growing community of scientists can publish its results and discuss its aims and methods. It welcomes papers which use the tools of physics in an innovative way to study biological problems, as well as research aimed at providing a better understanding of the physical principles underlying biological processes.
