Introduction:

An electron transport system (ETS) or electron transport chain (ETC) is a series of coenzymes and cytochromes that take part in the passage of electrons from one carrier to another and to its ultimate acceptor. The various components of ETS are arranged in five kinds of complexes, arranged in a definite sequence in the inner mitochondrial membrane.
