<span>ATP is used in the formation
of the polypeptide in the ribosome during translation. It induces the transport
of amino acid by tRNA. ATP is a pressure for the synthesis of RNA and DNA. As an
Adenosine Triphosphate, it is one of the 4 monomers nucleosides, when transformed
to dATP, that are used to synthesize DNA</span>.
ATP is also used to transport materials across
the cell membrane against a concentration gradient.
