The three golden lions on a red background, symbolising England, occupy the first and fourth quarters. The Arms of Scotland, a red lion rearing on its hind legs inside a red border, are in the second quarter, and the Arms of Ireland's golden harp with silver strings on a blue background-are in the third quarter.
Once it is reduced to QH2, ubiquinone delivers its electrons to the next complex in the electron transport chain. Q receives the electrons derived from NADH from complex I and the electrons derived from FADH2 from complex II, including succinate dehydrogenase. This enzyme and FADH2 form a small complex that delivers electrons directly to the electron transport chain, bypassing the first complex.
The octahedral ruthenium(II) complexes [Ru(Ln)(PPh3)2Cl2] [Ln = biphenyl furanyl pyridine derivatives] were synthesized and characterized using LCâMS, IR spectroscopy, elemental analysis and magnetic measurements. Complexes show enhancement in antibacterial activity compared to free ligands.
