Because all the mitochondrial DNA is inherited as a single unit, or haplotype, the relationships between mitochondrial DNA from different individuals can be represented as a gene tree.

If you have a mitochondrial disease, your cells aren’t able to produce enough energy. There isn’t a cure, but treatment can prevent life-threatening complications.

Jan 5, 2026 · Although mtDNA mutations play a role in some mitochondrial diseases, the majority of the conditions actually are the result of mutations in genes in the nuclear genome, which encodes a …

Jan 23, 2024 · A mitochondrion (plural: mitochondria) is an organelle in plants, animals, and fungi that produces chemical energy for cells. Mitochondria are the powerhouses of the cell.

May 27, 2025 · People often refer to mitochondria as the powerhouses of the cell. Their main function is to generate the energy necessary to power cells, but they are also involved in cell signaling and …

Oct 14, 2025 · Key Takeaways Mitochondria are the parts of cells that create energy for the body. Mitochondrial dysfunction can lead to diseases like Leigh syndrome and mitochondrial myopathy. …

Aug 31, 2024 · Mitochondria are responsible for producing and providing energy to our bodies, especially in organs such as the heart, brain, and muscles, which require high-energy production. …

Often described as the cellular ‘powerhouses’ due to their essential role in aerobic oxidative phosphorylation, mitochondria perform many other essential functions beyond energy production.

1 day ago · Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP). Mitochondria contain their own small chromosomes. Generally, …

The mitochondrial genome is vital for the mitochondria’s main role: burning the calories we eat with the oxygen we breathe to generate the energy to power all of our biological processes.
