How does ATP-ADP couple (link) endergonic and exergonic reactions?
Homework Answers
ATP is hydrolyzed into ADP in the following reaction:
ATP+H2O→ADP+Pi+free energy
Like most chemical reactions, the hydrolysis of ATP to ADP is reversible. The reverse reaction combines ADP + Pi to regenerate ATP from ADP. Since ATP hydrolysis releases energy, ATP synthesis must require an input of free energy.
ADP is combined with a phosphate to form ATP in the following reaction:
ADP+Pi+free energy→ATP+H2O
Cells couple the exergonic reaction of ATP hydrolysis with endergonic reactions to harness the energy within the bonds of ATP.
Or you can say the energy released from the hydrolysis of ATP into ADP is used to perform cellular work, usually by coupling the exergonic reaction of ATP hydrolysis with endergonic reactions.
I hope you understand everything, if you have any doubt just ask me.

ATP hydrolysis and the endergonic reaction that is coupled to it are usually represented as two separate equations. Explain why, if these where indeed two separate reactions, ATP hydrolysis will not be able to power the endergonic reaction? Does the answer have anything to do with the fact that ATP, although exergonic, is an incredibly stable molecule and will react slowly without the presence of an enzyme?
