The efficiency of energy transfer from foods to adenosine triphosphate (ATP) and of ATP utilization may also influence energy needs. In some forms of obesity, the obese may be more efficient than lean subjects in utilizing nutrients for resting metabolic requirements and, thus, may have more energy to store as fat (Sims et al., 1973).

Calculating ATP production rates can reveal the efficiency of energy transduction, and therefore what a cell or organism needs to survive and function. It can reveal the adaptability of ATP production to stresses, and therefore how energetically sensitive (or resistant) biological targets are to drugs or toxins.
Adenosine triphosphate (ATP) is the energy currency for cellular processes. ATP provides the energy for both energy-consuming endergonic reactions and energy-releasing exergonic reactions, which require a small input of activation energy. When the chemical bonds within ATP are broken, energy is released and can be harnessed for cellular work.
