    The chemical energy used for most cell processes is carried by ATP

    ATP (Adenosine Triphosphate) is a molecule that transfers energy from the breakdown of food molecules to cell functions.

    Energy is released when a phosphate group is removed and the ATP becomes ADP (adenosine diphosphate). 

    The ADP becomes ATP once again when a phosphate group is added back.
