mitochondrion

mi·to·chon·dri·on

 (mī′tə-kŏn′drē-ən)
n. pl. mi·to·chon·dri·a (-drē-ə)
A spherical or elongated organelle in the cytoplasm of nearly all eukaryotic cells, containing genetic material and many enzymes important for cell metabolism, including those responsible for the conversion of food to usable energy.

[New Latin : Greek mitos, warp thread + Greek khondrion, diminutive of khondros, grain, granule; see ghrendh- in Indo-European roots.]

mi′to·chon′dri·al (-drē-əl) adj.

mitochondrion

(ˌmaɪtəʊˈkɒndrɪən)
n, pl -dria (-drɪə)
(Biology) a small spherical or rodlike body, bounded by a double membrane, in the cytoplasm of most cells: contains enzymes responsible for energy production. Also called: chondriosome
[C19: New Latin, from Greek mitos thread + khondrion small grain]
ˌmitoˈchondrial adj

mi•to•chon•dri•on

(ˌmaɪ təˈkɒn dri ən)

n., pl. -dri•a (-dri ə)
an organelle in the cell cytoplasm that has its own DNA, inherited solely from the maternal line, and that produces enzymes essential for energy metabolism. Abbr.: mt See diag. at cell.
[1900–05; < Greek míto(s) thread + chóndrion small grain]

mitochondrion

mi·to·chon·dri·on

(mī′tə-kŏn′drē-ən)
Plural mitochondria
A structure in the cytoplasm of all cells except bacteria in which food molecules are broken down in the presence of oxygen and converted to energy in the form of ATP. Mitochondria contain their own DNA. See more at cell.

mitochondrion

(pl. mitochondria) A rod-shaped organelle inside a cell that is a site of energy release.

Historically, one theory suggests that mitochondrion was a bacterium that got caught in a eukaryotic cell two billion years ago.

It is important to point out that mitochondrial "dysfunction" does not mean that the mitochondrion is completely unable to synthetize ATP, but that means the functionality is affected or the organelle is sensitized to insults like calcium overload which is used in some of the experimental protocols; besides, the isolation process itself affects the organelle as can be appreciated with the control group.
Practically, a mitochondrion is a balloon inside the balloon where inner and outer membranes create two separate internal compartments: intermembrane space and matrix space [1].
Functionally, it was noted that each cell type exhibited heterogeneity in mitochondrial membrane potential (potential ([DELTA][psi]m)), as each cell type examined contained distinct populations of mitochondria having both high or low [DELTA][psi]m, and no single mitochondrion contained regions of high and low [DELTA][psi]m.
In the current study, we isolated cardiac mitochondrion RNA from a heart failure mice model and performed small RNA sequencing.
On one hand, the respiratory capacity and the cellular ATP levels are reduced, both key tasks of the mitochondrion, the powerhouse of the cell At the same time, all cells without HSP60 presented changes.

The mitochondrion (plural mitochondria) is a membrane-bound organelle found in most eukaryotic cells (the cells that make up plants, animals, fungi, and many other forms of life).
Wallace Professor of Biomedical Research and chair of comparative medicine at Yale School of Medicine, said that they have found that mitochondrion need to have ongoing dynamic plasticity in order to support neurons, which are necessary for appetite and for the maintenance of life.
However, quality control against oxidative damage is not restricted to the mitochondrion itself but is an integrated effort which involves a bidirectional cross talk between the entire mitochondria network and communication with other cellular quality control machineries like autophagy and the ubiquitin proteasomal system.
