Mitochondrial inner membrane


The mitochondrial inner membrane mtIM is the structure harboring the membrane-bound electron transfer system ETS including the respiratory complexes working as hydrogen ion pumps, the mt-phosphorylation system including the hydrogen ion pump ATP synthase, several substrate transporters involved in the electron transfer pathway, and a variety of other ion pumps that carry proton charge (Ca2+, Mg2+). The protonmotive force is the electrochemical potential difference across the mtIM generated by the hydrogen ion pumps of the .

Abbreviation: mtIM
