Coenzyme Q distribution within the cell is regulated by mitochondria

Antioxidants are often advertised as a cure-all in nutrition and offered as dietary supplements. However, our body also produces such radical scavengers itself, one of which is coenzyme Q. Now researchers from the Max Planck Institute for Biology of Ageing have discovered how the substance, which is produced in our mitochondria, reaches the cell surface and protects our cells from dying.
