ATP; nucleotide triphosphate

Explanation:

Biological food sources are broken down into a form of energy that cells use to do work. This usable form of energy is ATP, which is a nucleotide triphosphate.

The energy currency for all living cells is the ATP and this ATP is derived from aerobic or anaerobic breakdown of food sources during respiration.

ATP is known as Adenosine triphosphate, that is, Adenosine combining with three phosphate groups. The Adenosine represents a purine nucleotide which is also one of the constituents of Deoxy ribonucleic and ribonucleic acids.

Hence, the second option is the correct option.
