ATP is metastable (a thermodynamically unstable compound that does not rapidly break down in absence of a catalyst) and is commonly referred to as "free energy currency." Like monetary currency, ATP is used to provide energy in a wide variety of metabolic reactions and is universal among cells. Nevertheless, the energy content of ATP is not significantly different from other nucleoside di- and triphosphates. For whatever reason, however, evolution has created an array of enzymes that preferentially bind ATP and use its free energy of hydrolysis to drive endergonic reactions. Hydrolysis of either... 

ATP acts as the energy currency of the cell, transferring free energy derived from substances of higher energy potential to those of lower energy potential. 

We next quantitatively examine some of the ways in which ATP can be used as a free energy currency. Each of our four examples will relate to a different variable term in the chemical potential (fij = + RT In a j+... 

ATP hydrolysis provides most of the free energy required for living processes. ATP is ideally suited to its role as universal energy currency because its phosphoanhydride structure is easily hydrolyzed. 

ATP serves as the general "free energy currency" for virtually all cellular processes. Hydrolysis of ATP is used to drive countless biochemical reactions, including many that are not phosphorylations. It is a direct source of energy for cell motility, muscle contraction, and the... 

If ATP is the free energy "currency" of a cell, how does a cell synthesize a compound (such as creatine phosphate) with a much higher phosphate transfer potential than that of ATP ... 

J = 1 kg m2 s-2 Appendix II see Table 6-2). ATP is an extremely useful cellular energy currency because of its large free energy release upon hydrolysis — about 40 to 50 kJ mol-1 (10-12 kcal mol-1) —and because of its convenient form as a relatively abundant ion. 

Just as commerce is facilitated by the use of a common currency, the commerce of the cell—metabolism—is facilitated by the use of a common energy currency, adenosine triphosphate (ATP). Part of the free energy derived from the oxidation of foodstuffs and from light is transformed into this highly accessible molecule, which acts as the free-energy donor in most energy-requiring processes such as motion, active transport, or biosynthesis.
