Answer 2

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.
