Abstract:
The (3)MLCT excited state of Ru(II) complexes with 1,4,5,8-tetraazaphenanthrene (TAP) ligands in the presence of tryptophan gives rise to an electron transfer process from the amino acid with subsequent formation of an adduct between the two partners, strongly influenced by oxygen.

Photosystem I
Both these photosystems work in concert. An excited electron from PSII is relayed to PSI via an electron transport chain in the thylakoid membrane of the chloroplast, which is comprised of the carrier molecule plastoquinone, the dual-protein cytochrome complex, and plastocyanin. As electrons move between PSII and PSI, they lose energy and must be re-energized...
