Why is ATP an important molecule in metabolism?

• Its hydrolysis provides an input of free energy for exergonic reactions.

• It provides energy coupling between exergonic and endergonic reactions.

• Its terminal phosphate group contains a strong covalent bond that when hydrolyzed releases free energy.

• Its terminal phosphate bond has higher energy than the other two.
