Why is the phosphoanhydride bond between the phosphate group in ATP referred to as a high energy bond?

because...it is very unstable, thus allowing the third phosphate bond in ATP to be easily broken to release energy for anabolic reactions and to produce ADP.

What is the ATP cycle?
ATP (adenosine triphosphate) is an ubiquitous energy carrier molecule and it gives up its energy by breaking the phosphoanhydride bond between the last and second last phosphate groups and thereby phosphorylating (adding a phosphate to) a target molecule, most likely inducing a change in its conformation that leads to activation or direct action. When that bond is broken, the ATP loses one phosphate and becomes ADP (adenosine diphosphate), which is less energetic and infrequently used to provide additional energy for the cell. The ADP must then be 'recharged' during cellular respiration or photosynthesis where energy (derived from nutrients or light) is used to add a phosphate onto ADP, recreating the phosphoanhydride bond and producing ATP.
How does the molecule ATP store and release energy?
ATP is, on its own, a rather unstable molecule. Because of this, the conversion to a more stable molecule releases energy that can be used by other parts of the cell.
Where are high energy bonds found in ATP?
It has 2 high-energy phosphate bonds.
What is the function of adenosine triphosphate in a cell?
ATP stands for adenosine Di-phosphate. When cells need energy,then ATP can be broken down using water to release energy. It contain tri phosphate (three phosphate groups )
The energy available to the cell is stored in which part of the ATP molecule?
The energy that a cell can use to do work is the energy stored in the chemical bond between the second and third phosphate groups.

Where are the high energy bonds found in ATP?
between phosphate groups
What is released when a ATP looses a phosphate?
ATP (adinine triphosphate) loses a phosphate group to become ADP (adinine diphosphate). The phosphate group was released is referred to as inorganic phosphate. There is also a release of energy as the high energy phosphate bonds are cleaved.

Where are theses high energy bonds found in ATP?
Between the phosphate groups
What does respiration you?
ATP which stands for... Adenosine Tri Phosphate which is commonly referred as energy It also gives you oxygen.
When is the energy stored in ATP released?
The energy stored in ATP can be released by breaking the bond between the second and third phosphate groups. Therefore, the energy is released when a phosphate group is removed.

The energy of the Atp molecule is stored within which phosphate groups?
The energy of Atp molecules is not stored in any of its phosphate groups. Its energy is stored between and within the bonds of the phosphate groups of [Amp], Adp and Atp molecules.
The energy available to the cell is stored in which part of the ATP molecule?
The energy that a cell can use to do work is the energy stored in the chemical bond between the second and third phosphate groups.
Were does ATP store its energy?
When ATP is formed from ADP and free phosphate, energy is stored in the bond between the terminal phosphate and the rest of the molecule.When a cell requires energy, it breaks this bond, the terminal phosphate is freed, and a packet of energy is released for the cell to use.
