(a) Describe the structure of an ATP molecule. (b) How does the structure of the ATP molecule relate to the large amounts of free energy it contains?

A) ATP can be described as a phosphorylated sugar. It has a triphosphate group attached to a ribose sugar molecule, which is attached to a molecule of adenosine. b) Structure of ATP molecule permits it to contain large amounts of free energy; the unique feature that permits this is the triphosphate tail where several high energy bonds are located. These bonds can be recycled through cellular machinery.
