Obviously, the energy in living systems is stored in the bonds between phosphates of ATP (Adenosine Triphosphate). This energy is called bond energy. The high energy bonds are represented in squiggle symbol (~). The molecules of ATP is represented as A-P~P~P. So, the last two bonds in ATP are energy rich bonds.
I hope you know that ATP is converted to ADP+Pi and ADP+Pi to ATP.
(Pi= inorganic phosphate)
When one molecule of ATP is broken, it releases 7200 cal. of energy.

Yes
When a chemical bond forms, energy is absorbed between the atoms that bond. When a chemical bond is broken, energy is immediately and dramatically released.
During formation of bond,the atoms come close,then their are two possibilities 1. The force of attraction between electron of one atom and the nucleus of the other atom and the electron of the other atom attracts the nucleus of the another atom.This attractive forces lowers the potential energy of the two atoms and their are chances of bond formation. 2.There are also repulsive forces between nucleus-nucleus and electron-electron,which increases the potential energy. But as the attractive forces are dominant over the repulsive forces,therefore atoms come close and lower the energy of atoms forming bond.... During the formation of bond the potential energy of the atoms decreased.
Energy is absorbed, hence it is an endothermic process. The two atoms shared energy. Breaking them apart means they need energy replaced, which is taken from atmospheric heat.
the energy absorbed or released by atoms
When new bonds are formed between atoms, energy is released and this process is known as exothermic process. Similarly when old bonds break, energy from the surrounding is absorbed and is known as endothermic process.
Energy is stored in the potential energy of the electrons that make up that bond. This energy is released once the bond is broken.

The binding energy between atoms is released.
It is potential energy. It becomes kinetic when a bond is broken.
There is a repulsion force between electrons of two atoms and nucleus of same atoms. But if attractive force between nucleus of one atom and electrons of other atom must be more than repulsion force to make a bond. The excess repulsion force is released as energy during bond formation.
Have you heard of the term "bond energy"? The bonds between atoms of the same element, and atoms of different elements all contain a certain amount of energy. When a bond is broken, energy is released. When a bond is formed, energy is required. For example, two Carbon atoms bonding (they can have a C-C single bond, a C=C double bond, or a triple bond).

Energy in various way: for example heat.
CHEMICAL Chemical energy is stored in the bonds between atoms. This stored energy is released and absorbed when bonds are broken and new bonds are formed - chemical reactions. Chemical reactions change the way atoms are arranged. These reactions both absorb and release energy, but the net reaction releases energy.
Chemical energy is held in the bonds between the atoms of molecules and is released when these bonds are broken, as in burning. Such a reaction usually starts by applying heat to activate the burning process. As the chemical burns, bonds break, and energy escapes as heat and light.
