klorofüll a molekulide paar fotosüsteem II reaktsioonitsentris, mis absorbeerib maksimaalselt 680 nm valgust
Is the reaction-center chlorophyll a molecule in association with photosystem II. Its absorption spectrum peaks at 680 nm. Oxidized P680 (P680+) is the strongest biological oxidizing agent known. It has an estimated redox potential of ~1.3 V. This makes it possible to oxidize water during oxygenic photosynthesis.
Hea teada
Fotosünteesi elektrontransportahela komponent. Oksüdeerunud P680 (P680+) standard redokspotentsiaaliga + 1,3V on suuteline oksüdeerima vett, redutseerudes vee foto-oksüdeerumisel vabanevate elektronide poolt.
