Adenosine triphosphate (ATP) is the energy. Currency for celuclar processes. ATP provides the energy for both energy consuming endergonic reaction and energy releasing exerogonic reactions, which require a small input of activation energy. When the chemical bonds within ATP are broken, energy is relased and can be harnessed for celluar work. The more bonds in a molecule, the more potential energy it containsl. Because the bond in ATP is si easily broken and reformed, ATP is like a rechargeable battery that power callular processes ranging rfeom DNA replicatin to protein synthesis. Adenosine triphosphate (ATP) is comprising of the molecule adenosinek, bound to three phosphate groups. together, these chemical groups constitute energy powerhouse. Together the two bonds between the phosphates are equal high-energy bonds (phosphonhydride bonds) that, when broken release sufficient energy to power a variet of cellular reaction and processes. the bond between the beta and gamma phosphate is considered "hi-energy" because wnen the bond breaks, the products [adenosine diphosphate (ADP) and one inorgnic phosphate group (P_(1))is called hydrolysis because it concumes a water molecule (hydro, meaning "water" ,and lysis, meaning separation). ATP is hydrolyzed into ADP in the followinf reaction : ATP(aq)+H_(2)O(l)rarrADP(aq)+P_(i)(aq)+H_(3)O^(+)(aq)Delta_(r)=-30kJ//mol Like most chemical reactions, the hydrolysis of ATP to ADP is reversible. The reverse reaction combines ADP +P_(1) to regenerate ATP (adenosine diphosphate). Since ATP hydrolysis releases energy, ATP syntesis must require an input of free energy.
