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.
Electron transport and oxidative phosphorylation occur in the mitochondrion, the cell's power plant. The citric acid enzymes are housed there as is pyruvate dehydrogenase, enzymes for fatty acid oxidation, and all of the enzymes and proteins of the electron transport/oxidative phosphorylation system.eduction of molecular oxygen. Overview: The electron transport system (ETS) is a mechanism for capturing in the form of ATP, energy from the transfer of electrons from NADH and FADH2 to O2. During this process, the mitochondrion expels protons, creating a pH gradient across the mitochondrial membrane.
