Mitochondira are derived from mother cells. They conduct the ETC to produce energy or ATP. It is suggested by endosymbiosis theory that the early precursor engulfed mitochondria which was actually an energy producing bacteria. Mitochondria has its own DNA called as mtDNA.
Cells with high energy demands such as muscle cells, nerve cells, and cells in the heart would be most affected by mitochondrial cytopathies, as they rely heavily on mitochondrial function to generate energy in the form of ATP. Dysfunction in mitochondria would lead to impaired energy production, causing symptoms related to these tissues.

Researchers discovered that the mitochondrial DNA taken from heart cells of older adults showed more mutations and damage compared to younger individuals. This suggests that mitochondrial function deteriorates with age, which may contribute to age-related heart conditions.
Inner mitochondrial membrane
Some associated genes of human mitochondrial genome are the Eukaryotic cells and the cell nucleus. Mitochondrial DNA is inherited only from the mother's ovum.
ATP is produced for use by cells
ATP is produced for use by cells
It increases the surface for oxidative phosphorylation
Cells with mitochondria carry out oxidative phosphorylation. Oxidative phosphorylation involves the transfer of electrons in mitochondrial protein complexes that serve as electron donors and electron acceptors. The process yields molecular oxygen and energy in form of adenosine triphosphate.
Mitochondrial gene mutations can disrupt the energy production process in cells, leading to various disorders. These disorders can affect tissues with high energy demands, such as the brain, muscles, and heart. Symptoms can vary widely depending on which cells are impacted and the severity of the mutation.
