False-colour transmission electron micrograph of mitochondria from a hampster's adrenal cortex. Mitochondria are the sites of cell respiration: the chemical process which uses molecular oxygen to oxidise sugars & fats in order to produce energy. The energy is stored as adenosine triphosphate (ATP) & is used by the cell to drive chemical reactions such as protein formation. Mitochondria are bound by a double membrane. The inner membrane is folded to produce ingrowths (seen here) called cristae,which are where the chemical reactions of respiration occur. Yellow tint. Fawcett,The Cell,2nd edition,P.453 fig.242 | |
