The mitochondriaThe mitochondria are the bean-shaped organelles in the cells. They are the key organelles with responsibility for the production of ATP energy molecules. More are the bean-shaped organelles in the cells. They are the key organelles with responsibility for the production of ATPATP (adenosine triphosphate) molecules are the high-energy molecules with easily broken phosphate bonds that release energy to the energy-requiring processes in the cells. Coenzyme Q10 is essential to the process of ATP production. More energy molecules.
