Detailed explanation-1: -ATP is like a charged battery, while ADP is like a dead battery. ATP can be hydrolyzed to ADP and Pi by the addition of water, releasing energy. ADP can be “recharged” to form ATP by the addition of energy, combining with Pi in a process that releases a molecule of water.
Detailed explanation-2: -ADP also has high energy bonds located between each group. The presence of the third phosphate group and the additional high-energy bond between the second and third phosphate group in ATP enables it to store more energy than ADP, which does not have that third high-energy bond.
Detailed explanation-3: -When energy is required by cells, ATP is converted into ADP, adenosine diphosphate. During this process, the bond connecting the last and middle phosphates is hydrolyzed. This releases the energy stored within the bond.
Detailed explanation-4: -Cellular Level These bonds are high energy because of the associated electronegative charges exerting a repelling force between the phosphate groups. A significant quantity of energy remains stored within the phosphate-phosphate bonds.
