Question

The electron transport chain consist of 4 complex from which one electron is passed to another complex and derive the energy from electron movement for proton gradient generation.

The complex I is the first carrier, it accept the electron from the NADH which bring electron from the  Krebs cycle. This NADH pass it electron to ubiquinone by the oxidation of NADH to NAD+. So, the oxidation is of the NADH is the main mechanism involved in complex I that power the proton pump.
