The electron transport chain are the series of proteins that carry electrons through the membrane of the mitochondria. Mitochondria are the power house of the cells, they are made up of two cell membranes, the electrons transport chain takes place in the inner cell membrane.
The transportation of electrons through the mitochondrial membrane is also called oxidative phosphorylation. During the process of oxidative phophorylation, the energy release is capture in form of proton gradient and this is used to produce ATP via the process of chemiosmosis.
