[Factors of the optimization of the light-harvesting antenna structure of the photosynthetic unit].

The principles of model construction of pigment apparatus affecting the rate of energy trapping are analysed. The basic properties of the model system allowing optimization of this process are as follows: the spectral heterogeneity of light-harvesting pigment antenna; the proper mutual orientation of transition moment vectors of antenna molecules; the space arrangement of light-harvesting antenna molecules; the availability of "the focusing zone" of reaction centers, which is formed by the nearest to reaction centers antenna molecules.
