Mitochondria in cross section

Transmission electron micrograph of mammalian mitochondria in cross section. 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 or 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. Other cellular organelles are visible in the surrounding cytoplasm. Mag: x70, 000 at 10x8 inch size, x9, 100 at 35mm size
