Answer
Nucleotide that use in the formation of high energy molecule is known as Adenine.
Explanation
A single nucleotide is composed of three components, these are:
1. Pentose sugar
2. Phosphate group (phosphoric acid, and
3. Nitrogenous base.
Formation of high energy molecule
ATP stands for adenosine triphosphate is a type of mononucleotide. When adenine and nitrogenous base combine they give rise to another molecule known as adenosine.
Adenine + nitrogenous base → Adenosine
However when one phosphate group is attached to it it become adenosine monophosphate.
Adenosine + posphate → Adenosine monophosphate
Similary when another phosphate is attached it become adenosine diphosphate and the addition of third phosphate lead to the formation of adenosine triphosphate.
Conclusion
Thus is is cleared from the above discussion that Adenine is the main component of ATP (Energy rich molecule).
