It is a nucleotide composed of ribose, adenine, and a triphosphate group. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes such as biosynthesis, ion transport, and muscle contraction. ]]></termNote><termCreatedDate>2026-03-30 20:32:36</termCreatedDate><relation><relationType>UF</relationType><termId>31343345</termId><termName>ATP</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31343346</termId><termName>triphosphate, adenosine</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31319736</termId><termName>compounds</termName><termType>PT</termType></relation></term>  </Zthes>
