What is a really good description describing the function of Atp in Cells?

Answer 1

Adenosine tri-phosphate is the primary intra-Cellular energy transfer molecule found in Cells. Starting with Adenosine mono-phosphate (Amp) we add a [highly] negatively charged phosphate moiety to obtain Adenosine di-phosphate (Adp). It takes a huge amount of energy to add the third [highly] negatively charged phosphate group to the chain to form Adenosine tri-phosphate; and - like a popcorn kernel popping - this biochemical energy is released on demand on individual basis's throughout the Cell as needed, and when the enzymatically controlled biochemical reaction takes the energy released when Atp dissociates to Adp + p and stores it in chemical bonds elsewhere.

Repeat; this biochemically stored energy is translocated and used in all areas of the Cell.
