Understand the structure of ATP (adenosine triphosphate), which consists of an adenosine molecule bonded to three phosphate groups.
Recognize that ATP is a high-energy molecule used by cells to store and transfer energy.
Identify that the energy in ATP is primarily stored in the bonds between its phosphate groups, specifically the bonds between the second and third phosphate groups.
Learn that when ATP is hydrolyzed to ADP (adenosine diphosphate) and an inorganic phosphate, energy is released, which is used by the cell for various functions.
Conclude that the phosphate bonds, particularly the bond between the second and third phosphate groups, are where most of the energy in ATP is stored.
