Electron transport components on the way from reduced substrates to the terminal respiratory oxidase(s) are discussed in relation to analogous and/or homologous enzymes and electron carriers in the generally much better known bacteria, mitochondria and chloroplasts. The kinetic behaviour of the components, their localization within the cell and their evolutionary position are given special attention. Pertinent results from molecular genetics are also mentioned. The unprecedented role of cyanobacteria for our biosphere and our whole planet earth appears to deserve a more extended introductory chapter.
