Atp is considered to be an energy carrier molecule. where is the energy actually located in this molecule?

The energy is located in the phosphoanhydride bond, present between the phosphate groups in the ATP ( adenosine triphosphate) molecule.

There are two high energy chemical bonds present in the ATP. These are called as phosphoanhydride bonds. A high amount of energy is released when these bonds are broken down. When one phosphoanhydride bond is broken down, it releases 7.3 kcal/mol of energy.

Thus, the correct answer is phosphoanhydride bond.

69 is the correct math for the amino acids
