Complexes of the electron transport chain(ETC)
The electron transport chain comprises five protein complexes located in the inner membrane of mitochondria.
The components of the electron transport chain are arranged in order of their redox potential, from complex I to IV. The redox potential becomes more positive as we move from the beginning to the end of the chain, indicating that the start of the chain has a more negative redox potential.
This factor drives the movement of electrons along the chain from its starting point to its endpoint. These complexes form a functional unit capable of ATP production. A significant portion of these units are located in the inner membrane of mitochondria.
