Detailed explanation-1: -ATP is an energy rich molecule in which the energy is stored in the bonds between phosphate groups. Removal of one phosphate molecule from ATP forms ADP (Adenosine diphosphate ) releasing energy. One more phosphate molecule can be removed from this forming AMP (Adenosine monophosphate) and this further releases energy.
Detailed explanation-2: -When energy is needed immediately in the cell, ATP can be converted into ADP and an inorganic phosphate group. Breaking down the bond between the second and third phosphate groups converts ATP into adenosine diphosphate (ADP) and an inorganic 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: -The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups. ATP is commonly referred to as the “energy currency” of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups.
Detailed explanation-5: -Explanation: ATP is the primary energy currency for cells. The phosphoanhydride bonds of ATP, or the bonds between phosphate molecules, are high energy. This is due to the close proximity of positively charged phosphate and negatively charged oxygen; these charges repel.
