Mitochondrion. Coloured Transmission Electron Mic- crograph (TEM) of a mitochondrion (red) inside a cell, showing the double outer membrane and numer- ous internal membranes (cristae) where respiration takes place. The folded structure outside the mit- ochondrion (right) is rough endoplasmic reticulum, where proteins are manufactured. The green circles at left are secretory granules containing enzymes made by the cell. Mitochondria provide cells with energy by oxidising sugar and fat. They are found in almost all cells, have their own DNA, and replicate autonomously. This cell is from digestive enzyme-secreting (acinar) tissue from a bat's pancreas. Magnification unknown.
