Mitochondria are tiny structures located within nearly all cells of the body. They are the parts of the cell that are primarily responsible for creating energy. They do this by generating adenosine triphosphate (ATP), which is the essential “fuel” that drives all of the body’s functions. For this reason, mitochondria are often described as the “powerhouse” of the cell.
A single cell can have up to several thousands of mitochondria. Cells of the brain and muscle are among those that require a lot of energy, so they have a particularly high density of mitochondria to support their energy needs. When mitochondria aren’t working well, these are often the parts of the body to show signs of poor function.View Full Article
