Mitochondria of Vorticella convallaria like other ciliates, have tubular cristae arising from their inner membranes. However, they also have a bundle of filaments (DNA?) that extend through the center...

Ancistrum is a marine ciliate that inhabits the mantle cavity of mytiliid mussels. This image shows a good view of the macronucleus, mitochondria with tubular cristae, and what are probably flask-shap...

NRK cells expressing a mitochondria marker, mito-RFP (red), and PSS1-CFP (green), phosphatidylserine synthase 1. A single 6 micron confocal slice was imaged on a Zeiss LSM 510 every 5.9 sec with the...

This image shows a bovine pulmonary artery endothelial cell. The pulmonary artery is the large vessel that takes deoxygenated blood cells from the heart to the lungs. These cells have been stained wit...

Mitochondria are organelles enclosed by two membranes in which the inner membrane invaginates to form tubular cristae. The mitochondria shown here are typical of cells in late log phase of growth. Thi...

The tubular cristae of mitochondria bear a pair of protrusions when seen in cross section. These are the F1 subunits of F1F0 ATP synthase enzymes which play a role in producing ATP, the cell’s main ...

Isolated mitochondria that have been quick-frozen, fractured and deep-etched show some space between the inner and outer membranes. Arcs of tubules, where they are tangentially fractured, show the hel...

Quick-freeze deep-etch image of an unfixed and fractured mitochondrion. The tubular cristae average 50nm in diameter. Each cristae bears a helically arranged double row of particles with the particles...
