Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. ... NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP). In ATP the energy is stored in the form of chemical bonds.
