In type II reaction center proteins, the absorption of light initiates a vectorial [e.sup.-]-transport, that is, an electron is transferred from the specially organized chlorophyll or bacteriochlorophyll type primary [e.sup.-]-donor (P) to quinone (Q) acceptor molecules through redox active cofactor pigments (for review, see, e.g., [1, 38-40]).

Shamah explained the technology behind Tookad: Tookad was first synthesized in Scherz's lab from bacteriochlorophyll, the photosynthetic pigment of a type of aquatic bacteria that draw their energy supply from sunlight.

Direct evidence of long-lived quantum coherence was obtained by studying the Fenna-Matthews-Olson (FMO) bacteriochlorophyll complex, that acts as an energy 'wire' capable of connecting the chlorosome light-harvesting antenna to the reaction center where the plant converts photons to usable energy.
