It is a series of four protein complexes that contain two redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation.
The electron transport chain functions in the inner mitochondrial membrane.
The electron transport chain is responsible for the following:
The electron transport chain's main function is the generation of ATP that is used by cells for all processes.
The end products of electron transport are NAD+, FAD, water, and protons.
