Detailed explanation-1: -So the energy from cellular respiration is stored in the bond between the 2nd and 3rd phosphate groups of ATP. When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.
Detailed explanation-2: -A significant quantity of energy remains stored within the phosphate-phosphate bonds. Through metabolic processes, ATP becomes hydrolyzed into ADP, or further to AMP, and free inorganic phosphate groups. The process of ATP hydrolysis to ADP is energetically favorable, yielding Gibbs-free energy of-7.3 cal/mol.
Detailed explanation-3: -ATP consists of an adenosine molecule bonded to three phosphate groups in a row. During cellular respiration, energy in food is converted into chemical energy that can be used by cells. This chemical energy is stored in the pyrophosphate bond, which lies between the last two phosphate groups of ATP.
Detailed explanation-4: -During this process, the energy stored in glucose is transferred to ATP. Energy is stored in the bonds between the phosphate groups (PO4-) of the ATP molecule. When ATP is broken down into ADP (adenosine diphosphate) and inorganic phosphate, energy is released.
Detailed explanation-5: -The bonds between phosphate molecules are called phosphoanhydride bonds. They are energy-rich and contain a
