In brief
Tiny structures inside cells that generate most of the chemical energy the cell needs, stored in a molecule called ATP.
- Thyroid hormones regulate metabolism, including how much energy the body uses.
How it works
Mitochondria are membrane-bound structures, called organelles, inside your cells. The chemical energy they produce is stored in a small molecule called adenosine triphosphate (ATP), which powers the cell's chemical reactions.
Mitochondria contain their own small chromosomes. Generally, mitochondria, and so mitochondrial DNA, are inherited only from the mother. Faults in how mitochondria work can cause symptoms in the muscles, the brain and sometimes the kidneys.
