The energy used in the electron transport change pumps protons across the inner mitochondrial membrane from the inner matrix to the intermembrane space, producing a strong hydrogen concentration gradient.
In the mitochondrial electron transport chain electrons move from an electron donor (NADH or QH 2) to a terminal electron acceptor (O 2) via a series of redox reactions.These reactions are coupled to the creation of a proton gradient across the mitochondrial inner membrane.n the mitochondrial electron transport chain electrons move from an electron donor (NADH or QH 2) to a terminal electron acceptor (O 2) via a series of redox reactions.
