Semiautonomous, self-reproducing organelles that occur in the cytoplasm of all cells of most, but not all, eukaryotes. Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae. Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. They contain distinctive RIBOSOMES, transfer RNAs (RNA, TRANSFER); AMINO ACYL T RNA SYNTHETASES; and elongation and termination factors. Mitochondria depend upon genes within the nucleus of the cells in which they reside for many essential messenger RNAs (RNA, MESSENGER). Mitochondria are believed to have arisen from aerobic bacteria that established a symbiotic relationship with primitive protoeukaryotes. (King and Stansfield, A Dictionary of Genetics, 4th ed)

Mitochondria, Muscle

Mitochondria of skeletal and smooth muscle. It does not include myocardial mitochondria for which MITOCHONDRIA, HEART is available.

Year introduced: 1968

Mitochondria, Liver

Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix. (From Alberts et al., Molecular Biology of the Cell, 2d ed, p343-4)

Mitochondria Associated Membranes

Specialized areas of the endoplasmic reticulum in close physical contact with MITOCHONDRIA. These inter-organelle contact sites participate in the regulation of various processes such as MITOCHONDRIAL DYNAMICS; CALCIUM SIGNALING; ENERGY METABOLISM and INFLAMMATION.

Mitochondrial Size

The quantity of volume or surface area of MITOCHONDRIA.

Year introduced: 2007

Select item 680283617.

Mitochondrial Diseases

Diseases caused by abnormal function of the MITOCHONDRIA. They may be caused by mutations, acquired or inherited, in mitochondrial DNA or in nuclear genes that code for mitochondrial components. They may also be the result of acquired mitochondria dysfunction due to adverse effects of drugs, infections, or other environmental causes.

Mitochondrial Swelling

An increase in MITOCHONDRIAL VOLUME due to an influx of fluid; it occurs in hypotonic solutions due to osmotic pressure and in isotonic solutions as a result of altered permeability of the membranes of respiring mitochondria.

Barth Syndrome

Rare congenital X-linked disorder of lipid metabolism. Barth syndrome is transmitted in an X-linked recessive pattern. The syndrome is characterized by muscular weakness, growth retardation, DILATED CARDIOMYOPATHY, variable NEUTROPENIA, 3-methylglutaconic aciduria (type II) and decreases in mitochondrial CARDIOLIPIN level. Other biochemical and morphological mitochondrial abnormalities also exist.
