What two molecules do cells need to make energy

Glucose and ATP. Two of the most important energy-carrying molecules are glucose and ATP (adenosine triphosphate).

Explanation:

All organisms make use of a molecule called glucose and a process called glycolysis to meet some or all of their energy needs. For single-celled prokaryotic organisms, such as bacteria, this is the only process available for generating ATP (adenosine triphosphate, the "energy currency" of cells).
