How is energy stored in atp

Briefly describe how energy that is released from energy-containing compounds is trapped and stored as ATP and how energy stored in ATP is released to do cellular work. Flash animation illustrating the hydrolysis of ATP to provide energy for cellular work.

Summary Cellular energy is primarily trapped and stored in the form of adenosine triphosphate or ATP. The energy is stored in these high-energy phosphate bonds. To obtain energy to do cellular work during endergonic anabolic chemical reactions, the organism enzymatically removes the third phosphate from ATP thus releasing the stored energy and forming ADP and inorganic phosphate once again.

Now its back to being ADP and is ready to store the energy from respiration by bonding with a 3rd phosphate group. How does atp store and release energy?

Adenosine Triphosphate. The covalent bond holding the third phosphate group carries about 7, calories of energy. They function as fuel molecules, storing large quantities of energy in a stable form over long periods of time.

They are the long-term energy currency of the cell. For "pocket change", cells require a molecule that stores much smaller quantities of energy, that can be used in synthetic reactions like the formation of sucrose, and that can be used over and over again.
