Cytochrome C Oxidase - an overview ScienceDirect Topics
Cytochromes are redox-active proteins containing a heme, with a central iron (Fe) atom at its core, as a cofactor. They are involved in electron transport chain and redox catalysis. They are classified according to the type of heme and its mode of binding. Four varieties are recognized by the International Union of … See more Cytochromes were initially described in 1884 by Charles Alexander MacMunn as respiratory pigments (myohematin or histohematin). In the 1920s, Keilin rediscovered these respiratory pigments and named them … See more The heme group is a highly conjugated ring system (which allows its electrons to be very mobile) surrounding an iron ion. The iron in cytochromes usually exists in a ferrous (Fe ) and a … See more • Scripps Database of Metalloproteins • Cytochromes at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more WebWhich component of the electron-transport chain most likely contains an iron–sulfur cluster? a: ubiquinone b: cytochrome c reductase complex c: NADH dehydrogenase complex d: cytochrome c oxidase complex e: cytochrome c Expert Answer 100% (14 ratings) Answer part 1 E is the correct option.
