Which way of representing a molecule best shows its three-dimensional shape?

The best way to show the three dimensional shape of a molecule is to use the space filling molecular model also called Calotte model.  Calotte model is a type of three dimensional molecular model where atoms are arranged in such a way that atoms are represented by coloured spheres which take into account the radii of the real atoms. This model help the students to grasp the manner in which atoms and bonds are arranged in chemical compounds. 

This is what i found on google “when one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and atp is converted to adenosine diphosphate (adp). likewise, energy is also released when a phosphate is removed from adp to form adenosine monophosphate (amp).” i hope this you .
