Respuesta :

ATP stands for adenosine triphosphate. ATP is composed of three components. At the center of the molecule is found ribose, a sugar molecule which is the very same sugar that forms part of the RNA.
So to answer your question the answer to this should be Phosphorous.

Hope this helped :)
Have a great day

Answer:

The key component of the energy molecule, ATP is the ribose.

Explanation:

The ATP molecule is formed by one Adenosine (Adenine + Ribose) and three Phosphate molecules. The bonds that keep the second and third phosphate radicals trapped in the ATP are very energetic. Thus, every time the third phosphate comes loose from the set, energy will release to hold it together with ATP. The chemical bonds between two of the ATP phosphates are graphically represented by the ~ (tilde) symbol.

Ribose is the main component of this system, besides being the largest, where the bonds are established.
