Description

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 energy source. TEM taken on 3/7/80 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 22,500X. Bar = 0.25µm.

Technical Details

Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness. The negative was printed to paper and the image was scanned to Photoshop. This digitized image is available for qualitative analysis.
