This process is carried out by five membrane-bound complexes collectively known as the respiratory chain, working in concert to transfer electrons and pump protons. The precise organization of these complexes in native cells is debated. We used in situ cryo-electron tomography to visualize the native structures and organization of several major mitochondrial complexes in cells. ATP synthases and respiratory complexes segregate into curved and flat crista membrane domains, respectively. Respiratory complexes I, III, and IV assemble into a respirasome supercomplex, from which we determined a native 5-angstrom (Å) resolution structure showing binding of electron carrier cytochrome . Combined with single-particle cryo-electron microscopy at 2.4-Å resolution, we model how the respiratory complexes organize inside native mitochondria.
