	Mitochondrion - Elsevier
		Mitochondrion is a definitive, high profile, peer-reviewed international research journal.
		The scope of Mitochondrion is broad, reporting on basic science of mitochondria from all organisms and from basic research to pathology and clinical aspects of mitochondrial diseases.
		The journal welcomes original contributions from investigators working in diverse sub-disciplines such as evolution, biophysics, biochemistry, molecular and cell biology, genetics, pharmacology, toxicology, forensic science, programmed cell death, aging, cancer and clinical features of mitochondrial diseases.

	Mitochondrion - Wikipedia, the free encyclopedia
		In cell biology, a mitochondrion (plural mitochondria) (from Greek mitos thread + khondrion granule) is an organelle, variants of which are found in most eukaryotic cells.
		Mitochondria are sometimes described as "cellular power plants," because their primary function is to convert organic materials into energy in the form of ATP via the process of oxidative phosphorylation.
		A mitochondrion contains outer and inner membranes composed of phospholipid bilayers and proteins.

	Mitochondrion (Site not responding. Last check: )
		In cell biology a mitochondrion is an organelle found in the cells of most eukaryotes.
		"Mitochondrion" literally means 'thread granule' which what they look like under a light microscope : tiny rod-like structures present in the cytoplasm of all cells.
		Essentially this widely accepted hypothesis postulates the ancestors of modern mitochondria were independent that colonized the interior of the ancient precursor of all eukaryotic life.

	Mitochondria
		I suggest that the contact between mitochondrion and neuron might be rather like the contact of two neurons at a synapse, except of course that the mitochondrion is inside the neuron (not outside it), and is smaller than a typical synapse.
		And it is possible that the positive charge of the protons outside the inner membrane of the mitochondrion is balanced, partly or wholly, by the negative charge of anions inside the inner membrane, so that the protons on the outside are 'tied' by the attractive force between them and the anions.
		When the mitochondrion exhausts (or nearly exhausts) the supply of ATP inside it the ATPase has to stop using ATP as a fuel; it then rotates in the reverse direction and is driven as ATPsynthase by the flow of protons from outside the inner membrane to inside.

	Mitochondrion
		The mitochondrion is an organelle most eukaryotic cells host, including plants, animals, fungi, and protozoa.
		In some cells, there is only a single large mitochondrion; but in most cells, hundreds or thousands of mitochondrion can be found; in highly active cells, more mitochondria are found.
		The mitochondrion contains its own DNA, and was probably an independent organism back at the dawn of life that was captured and became an inseparable symbiote.

		This is a three-dimensional reconstruction of a dendritic mitochondrion from chick cerebellum reconstructed tomographically from a tilt series of a 0.5 micron section.
		These range from the red crista at upper right which is a single tubule through somewhat more complex cristae with several tubular crista junctions to the inner boundary membrane to the large yellow crista consisting of a large lamellar compartment with many crista junctions.
		Two segments of the endoplasmic reticulum adjacent to the mitochondrion are shown in light brown and green.

		This cycle is also known as the TCA (tricarboxylic acid) cycle and the citric acid cycle.
		This is further evidence for the origin of the mitochondrion as a prokaryotic endosymbiont.
		The genetic code used in the mitochondrion is slightly different than that of eukaryotic cells as well.

	Cellular Respiration
		Each of these protein complexes also requires subunits that are encoded by nuclear genes, synthesized in the cytosol, and imported from the cytosol into the mitochondrion.
		Presumably, very early in their embryonic development, a mutation occurred in a cytochrome b gene in the mitochondrion of a cell destined to produce their muscles.
		The reason for this is probably the extensive mixing of mutant DNA and normal DNA in the mitochondria as they fuse with one another.

	Iron trafficking in the mitochondrion: novel pathways revealed by disease -- Napier et al. 105 (5): 1867 -- Blood
		Iron in the labile pool is thought to regulate the mRNA-binding activity of the iron-regulatory proteins (IRP1 and IRP2) that are important for regulating the expression of TfR1 and ferritin, which are critical for Fe uptake and storage, respectively.
		Iron is supplied to the mitochondrion from the cytosolic labile Fe pool by an unknown mechanism.
		Two atoms of Fe are delivered to the cluster machinery and the [Fe-S] cluster components are rearranged to form a single [2Fe-2S] cluster that is bridged between the 2 IscU subunits.

		RB: Having said that the DNA in this particular mitochondrion resembles bacterial DNA, is it particularly close to any kind of bacteria, because that in turn would be quite fascinating, it would give some clue as to the kind of bacterium that might have formed the original mitochondrion.
		MG: Yes, perhaps the biggest surprise is that the enzyme that is actually responsible for expressing mitochondrial DNA, that enzyme is called RNA polymerase, and in bacteria the enzyme is made up of four different proteins, and so we would have expected that the mitochondrial RNA polymerase would be like a bacterial RNA polymerase.
		RB: Now, finally, Michael, you've obviously found something which is rather like the original mitochondrion, but perhaps it's not the granddaddy of them all, perhaps you're going to go back to other protozoons or other organisms, and see if you can find something which is even more primitive.
