The mitochondrion (plural mitochondria) is a double membrane-bound organelle found in all eukaryotic organisms, although some cells in some organisms may lack them (e.g. Red blood cells). A number of organisms have reduced or transformed their mitochondria into other structures. To date, only one eukaryote is known to have completely lost its mitochondria. The word mitochondrion comes from the Greek mitos, i.e. “thread”, and chondrion, i.e. “granule” or “grain-like”.

Mitochondria are commonly between 0.75 and 3µm in diameter but vary considerably in size and structure. Unless specifically stained, they are not visible. Mitochondria have been described as “the powerhouse of the cell” because they generate most of the cell’s supply of adenosine triphosphate (ATP), used as a source of chemical energy. In addition to supplying cellular energy, mitochondria are involved in other tasks, such as signaling, cellular differentiation, and cell death, as well as maintaining control of the cell cycle and cell growth. Mitochondria have been implicated in several human diseases, including mitochondrial disorders, cardiac dysfunction, and heart failure. In 2014, a study including ten children diagnosed with severe autism suggests that autism may be correlated with mitochondrial defects.

The number of mitochondria in a cell can vary widely by organism, tissue, and cell type. For instance, red blood cells have no mitochondria, whereas liver cells can have more than 2000. The organelle is composed of compartments that carry out specialized functions. These compartments or regions include the outer membrane, the intermembrane space, the inner membrane, and the cristae and matrix. Mitochondrial proteins vary depending on the tissue and the species. In humans, 615 distinct types of protein have been identified from cardiac mitochondria, whereas in rats, 940 proteins have been reported. The mitochondrial proteome is thought to be dynamically regulated. Although most of a cell’s DNA is contained in the cell nucleus, the mitochondrion has its own independent genome that shows substantial similarity to bacterial genomes.

  1. This was great, thanks, I have been researching "mitochondria supplements" for a while now, and I think this has helped. Ever heard of – Miyason Mitochondria Masker – (should be on google have a look ) ? Ive heard some incredible things about it and my work buddy got amazing success with it.
