Energy from food must be transformed into the bonds of before it can be used by cells

it would be ATP or adenosine triphosphate

All energy gained will be converted into ATP molecule. When the organism needs energy, the phosphate bond in ATP molecule can be removed to produce the energy stored. In this reaction, the ATP will change into adenosine diphosphate or ADP

The answer is ATP. ATP is the universal energy for all chemical reactions. For your body to use energy from food it must be turned into energy your cells can use.
