Cells derive energy by performing cellular respiration. The usable form of energy required by living cells is stored as <em>ATP which has three phosphate groups and thus gets the name Adenosine Triphosphate. </em>Within cells glucose molecules and oxygen react to form carbon dioxide, water and ATP.
<em>ATP is formed by the combination of ADP and a phosphate group</em> and is used for energy storage. It is the energy of the bonds in glucose molecule that gets transferred to the phosphate groups in ATP. <em>If energy has to be released this ATP has to break down into ADP and phosphate.
