Electron Transport Chain

The metabolic pathway through which the electron passes from one carrier to
another inside the inner mitochondrial membrane is called ETC or mitochondrial

respiratory chain.
Electrons from NADH produced during citric acid cycle are oxidized by NADH

dehydrogenase and electrons are transferred to ubiquinone located within the inner

membrane. Ubiquinone also receives electrons from FADH2 which is transferred to
cytochrome c via cytochrome bc complex.
