A model of the bovine mitochondrial ATP synthase at 32 Angstrom resolution as determined by electron cryomicroscopy of detergent solubilized single particles obtained from heart mitochondria. A render...

Here a mitochondrion is sliced approximately through its midplane, so both its outer membrane and the infoldings of its inner membrane are clearly seen. The organization of the inner membrane is parti...

The F1F0 ATP synthase is a large protein complex that catalyzes the formation of ATP from ADP and inorganic phosphate using a proton gradient as a source of energy. In eukaryotes, the F1F0 ATP syntha...

Transmission electron micrograph of mitochondria and lipid droplets from guinea pig pancreas. The use of osmium tetroxide as a fixative for electron microscopy was first described by Dr. Palade at the...

In insect spermiogenesis, mitochondrial cristae disappear and a proteinaceous material is deposited in filaments that become closely packed paracrystalline arrays. In this micrograph, crystals are pr...

The inner segment of photoreceptors in the retina is packed with long, thin mitochondria that contain curved cristae. This image by Toichiro Kuwabara is of a photoreceptor from human retina, and appe...
