Oxidative phosphorylation is the the synthesis in the The mitochondria are the bean-shaped organelles in the cells. They are the key organelles with responsibility for the production of ATP energy molecules. More during aerobic respiration of ATP (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 by phosphorylation of ADP molecules. It is the final stage of the process of Cellular respiration is the technical term for the metabolic reactions and processes in the cells that convert the biochemical energy from nutrients into adenosine triphosphate (ATP) energy and then release waste products.
