Detailed explanation-1: -The bond between the sugar and phosphates are broken and release energy. The bond between the second and third phosphate are broken to release energy.
Detailed explanation-2: -When a phosphate group is removed from ATP, energy is released and ADP results.
Detailed explanation-3: -The energy released from the hydrolysis of ATP into ADP + Pi is used to perform cellular work. Cells use ATP to perform work by coupling the exergonic reaction of ATP hydrolysis with endergonic reactions. ATP donates its phosphate group to another molecule via a process known as phosphorylation.
Detailed explanation-4: -The phosphate tail of ATP is the actual power source which the cell taps. Available energy is contained in the bonds between the phosphates and is released when they are broken, which occurs through the addition of a water molecule (a process called hydrolysis).
Detailed explanation-5: -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.
