The right answer is ATP.
ATP (Adenosine tri-phosphate) is a nucleotide, that is to say a molecule formed by a sugar with 5 carbon atoms, deoxyribose, a nitrogenous base, adenine, and a chain of three phosphoric acids .
The three parts of the ATP molecule are well distinguished: 5-carbon sugar (ribose), the nitrogen base (adenine) and the three phosphate groups, loaded under physiological conditions.
