16/01/2014 · The mitochondrial chromosome. Given the importance of mtDNA-encoded genes for mitochondrial function, it is not surprising that there are dedicated mechanisms that actively control the structure and distribution of mitochondria and mtDNA, but in higher eukaryotes, these mechanisms are divergent from those of their ancestors 22.
Summary. Oxidative phosphorylation (OXPHOS) has a prominent role in energy metabolism of the cell. Being under bigenomic control, correct biogenesis and functioning of the OXPHOS system is dependent on the finely tuned interaction between the nuclear and the mitochondrial genome.

The intermembrane space is the narrow space between the outer membrane and the inner membrane, while the mitochondrial matrix is the area that is completely enclosed by the innermost membrane.

Apart from these main functions, mitochondria are also involved in cellular process like regulation of membrane potential, induction of apoptosis, regulation of cellular metabolism, synthesis of heme (porphyrin), and synthesis of some steroids.
Mitochondrial structure and function are dynamic and closely linked, therefore analyzing mitochondrial structure can provide clues to the status of mitochondrial health (Sarasija and Norman, 2015).
