Detailed explanation-1: -The correct answer is (C). The majority of energy in an ATP molecule is stored in the bond between the last and middle phosphate groups.
Detailed explanation-2: -This chemical energy is stored in the pyrophosphate bond, which lies between the last two phosphate groups of ATP. When the cells need energy to do any work, ATP cleaves the third phosphate group, releasing a large amount of energy stored in the bond between the third and second phosphate group.
Detailed explanation-3: -This occurs when a molecule of adenosine diphosphate (ADP) uses the energy released during cellular respiration to bond with a third phosphate group, becoming a molecule of ATP. So the energy from cellular respiration is stored in the bond between the 2nd and 3rd phosphate groups of ATP.
Detailed explanation-4: -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).
