For reaction centers of photosynthetic bacteria reconstituted with low-potential quinones in the Q A sit , the state PQA formed by light activation decays to the ground state via a thermally activated route through the P+Hstate. The rate of charge recombination by this thermal pathway is proportional to the equilibrium constant between P QA and P+H-. Thus… CONTINUE READING
