Unlike eukaryotic cells in which the electron transport system is located on mitochondria, the electron transport system of bacteria is located on the cytoplasmic (plasma) membrane, which is best described as a lipoprotein bilayer. Since prokaryotes possess no internal membrane -bound organelles, all biochemical processes that require membrane support must occur on the internal surface of the cytoplasmic membrane.
