Final answer:
The hydrolysis of a phosphate from adenosine-5'-triphosphate (ATP) is the most thermodynamically favorable, releasing a large amount of energy. This reaction forms adenosine-5'-diphosphate (ADP) and one inorganic phosphate molecule.
Step-by-step explanation:
The hydrolysis of a phosphate from adenosine-5'-triphosphate (ATP) is the most thermodynamically favorable. ATP is an energy-rich molecule that contains three phosphate groups, which are all high-energy bonds. The hydrolysis of the phosphate group in ATP releases a large amount of energy that can be used for cellular processes.
When the bond between the second and third phosphate groups in ATP is broken, it forms adenosine-5'-diphosphate (ADP) and one inorganic phosphate molecule. This hydrolysis reaction is exergonic and releases energy.
Therefore, the hydrolysis of a phosphate from ATP is the most thermodynamically favorable.
