WebFeb 27, 2024 · The O(2) reduction site of cytochrome c oxidase (CcO), comprising iron (Fe(a3)) and copper (Cu(B)) ions, is probed by x-ray structural analyses of CO, NO, and CN(-) derivatives to investigate the mechanism of the complete reduction of O(2). WebCytochrome c forms one connection in a hard-wired cellular electronic circuit. It transfers electrons at the last step in the production of cellular energy. These electrons are originally obtained through the breakdown of sugar, and end up being attached to oxygen to form water (this is the ultimate fate of the oxygen that we breathe).
