Answer 1

Chemical potential energy

Explanation:

Since `ATP` is a huge molecule, there are a lot of bonds stored within that molecule. In those bonds, there is chemical potential energy, waiting to be released, especially in the phosphate `(PO_4^(3-))` groups in the molecule. In the second and third phosphate groups, they are broken down into `ADP` and energy. Have a look at this picture of an `ATP` molecule:

There are so many bonds here, and many, if not all are covalent. These types of bonds are very strong, and therefore have a lot of energy in them.

So, the energy stored within an `ATP` molecule is in the form of chemical potential energy.

Answer 2

The energy stored in ATP is potential chemical energy.

Explanation:

`"ATP"` is adenosine triphosphate, which means it is a molecule of adenosine (adenine and ribose) chemically bonded to three phosphate groups. The chemical bond between the second and third phosphate groups is a high energy bond. When that bond is broken, energy is released, producing `"ADP"` (adenosine diphosphate). The energy released is used by the cell to do work. During cellular respiration, `"ATP"` is produced by the addition of a third phosphate group to `"ADP"` molecules.
