In cell biology, a mitochondrion (plural mitochondria) (from Greek μιτος or mitos, thread + κουδριον or khondrion, granule) is a membrane-enclosed organelle, found in most eukaryotic cells. Mitochondria are sometimes described as "cellular power plants," because they convert food molecules into energy in the form of ATP via the process of oxidative phosphorylation. A typical eukaryotic cell contains about 2,000 mitochondria, which occupy roughly one fifth of its total volume. Mitochondria contain DNA that is independent of the DNA located in the cell nucleus.

Glutamate dehydrogenase (GDH, EC 1.4.1.2)
has long been used as a marker for
mitochondria in brain and other tissues, despite reports
indicating that GDH is also present in nuclei of liver and
dorsal root ganglia. Our results indicate that GDH is present in
both nuclei and mitochondria in rat brain. The notion that GDH
may serve as a marker for mitochondria needs to be re-evaluated.

mitochondria.

other lineages is targetted to the mitochondrial compartment.
PMID: 9247927
Hsp78
is a Clp homologue within mitochondria of
Saccharomyces cerevisiae. hsp78 can partially substitute for
mt-hsp70 functions in the assembly of mitochondria and may be
part of a salvage pathway if mt-hsp70 is limiting.

mtDNA
the G allele of the mitochondrial DNA (mtDNA) polymorphism at nucleotide position 11719 is associated with the European mtDNA haplogroup cluster HV, and that 11719A is therefore the ancestral allele. PMID: 11236862
N-acetyl aspartate
a marker for neuronal loss or mitochondrial
dysfunction.

Cu/Zn SOD to mitochondria. The characteristic Cu/Zn SOD profile
