Adenine Ribose Phosphate ATP ADP Ribose Ribose Adenine Adenine Triphosphate Diphosphate Phosphate Phosphate removed added to ADP Energy is stored in the ATP molecule Energy is released for cell work Mitochondria. Site of respiration. C6H12O6 + O2 Sun ALL living things. Chloroplast. ATP Site of photosynthesis. CO2 + H20 Green plants only.
