Mitochondria Mitochondria are tiny organelles found in nearly all eukaryotic cells. They are rather large organelles ranging from 0.5µm to 10µm in length and 1µm in diameter. The mitochondria are the energy factories of the cell and are located in the cytoplasm. They are the sites of cellular respiration. The mitochondria are responsible for generating ATP from such organic fuels as simple sugars and fats in the process of cellular respiration.

Cells that use energy at a high rate contain large numbers of mitochondria to make replacement ATP. Muscle cells and heart cells are cells with high energy requirements, that contain many mitochondria. Mitochondria have their own genetic material and can reproduce themselves within living cells. Most cells contain mitochondria which are organelles with elaborate internal membranes.
