Understanding Mitochondrial Myopathy
Our muscles need energy to function. That energy comes from our mitochondria.
Mitochondria are tiny structures inside almost every cell in our bodies. Each person has trillions of them working to convert oxygen and food into a special type of energy called adenosine triphosphate, or ATP. 90% of the energy our muscles need comes from ATP.
Some cells have a single mitochondrion while others contain hundreds of them. Someone who does not have enough healthy mitochondria, in one or several muscle groups, is said to have mitochondrial myopathy, or mitochondrial disease.
