Transmission electron micrograph (TEM) of a mitochondrion, the large oval structure, in a cell from the pancreas of the bat, Myotis lucifugus. Mitochondria are found in all eukaryotic cells, whether plant or animal, where they are the site of cell respiration - the chemical process which uses molecular oxygen to oxidise sugars & fats in order to produce energy. The mitochondrion in this picture is surrounded by endoplasmic reticulum, part of the membrane system of the cytoplasm. Magnification unknown.
