False-colour transmission electron micrograph of mammalian mitochondria (green) in cross-section. Mitochondria are the sites of cell respiration - the chemical process which uses molecular oxygen to oxidise sugars & fats 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 (red lines) called cristae,which are where the chemical reactions of respiration occur. Other cellular organelles are visible in the surrounding cytoplasm. Magnification: x18,200 at 6x4.5cm size | |
