ATP (adenosine triphosphate) is complex organic biomolecule that provides energy to all living organisms. ATP is produced by a chemical reaction, in which an inorganic phosphate molecule binds with ADP (adenosine diphosphate) molecule.
ATP is important to the cells as it is considered as energy currency of the cell, which is required for various functions, performed by a living cell, such as chemical synthesis of compounds, muscle contraction, and propagation of nerve impulses.
