In the electron transport chain, cyt ''c'' shuttles electrons between the respiratory complexes III and IV. Initially, the heme iron is in the reduced, Fe<sup>3+</sup> state; this allows for the uptake of one electron, oxidizing the iron to the Fe<sup>2+</sup> state.<ref name='etc'>ISBN:10-0-470-04217-6</ref>
In the electron transport chain (ETC), cyt ''c'' shuttles electrons between the respiratory complexes III and IV; complex III is the cytochrome ''bc''<sub>1</sub> complex and IV is cyt ''c'' oxidase. Initially, the heme iron in cyt ''c'' is in the reduced, Fe<sup>3+</sup> state; this allows for the uptake of one electron, oxidizing the iron to the Fe<sup>2+</sup> state.<ref name='etc'>ISBN:10-0-470-04217-6</ref> The ETC in eukaryotes is quite simple compared to that of prokaryotes.
