    Cytochrome c is an integral part of the mitochondrial respiratory chain. It is confined to the intermembrane space of mitochondria, and has the function of transferring electrons between its redox partners. Solution studies of cytochrome c indicate that the conformation of the molecule is sensitive to the ionic strength of the medium.
