All organisms require a constant supply of energy to maintain their cells and stay alive
This energy is required:
- In anabolic reactions – building larger molecules from smaller molecules
- To move substances across the cell membrane (active transport) or to move substances within the cell
- In animals, energy is required:
  - For muscle contraction – to coordinate movement at the whole-organism level
  - In the conduction of nerve impulses, as well as many other cellular processes
In all known forms of life, ATP from respiration is used to transfer energy in all energy-requiring processes in cells
This is why ATP is known as the universal energy currency
Adenosine Triphosphate (ATP) is a nucleotide
- The monomers of DNA and RNA are also nucleotides
