Abstract

In the primary reactions of photosynthesis, the light-induced charge separation and stabilization involves the generation of a radical cation and of radical anions at the various steps of electron transfer. In the reaction centers, specialized pigment molecules and redox components act as primary electron donors and electron acceptors. They are embedded in the protein matrix and provided with very specific interactions that seem to be responsible for the spectral and redox properties of the pigments as well as for the efficiency and specificity of electron transfer.
