When a phosphate group is removed from ATP, what is released? then removing this phosphate creates what???

ATP is a molecule consisting of a nitrogenous base, adenosine, bonded to three phosphate groups. So, when ATP is cleaved to ADP (with two phosphate groups rather than 3), a phosphate group is released (including a phosphorus atom and 4 oxygen atoms). Because ATP is fairly unstable, there is a favorable energy change ociated with this release and the reaction is often coupled with other reactions your body wants to use in order to drive them forward, so you might say that energy is released when the phosphate group is removed.
