i looked everywhere but didnt find anything with good comparisons

energy in these molecules is stored in the bonds between phosphate groups. atp is adenosine triphosphate, it has three phosphate groups, and adp is adenosine diphosphate. so atp produces more energy, although i don't know exactly how much more.

ATP. ATP stands for Adenosine Triphosphate. It's comprised of a sugar group ribose with a nitrogenous base (Adenine) and "Tri" phosphates - 3. It is in the third bond between the 2 and 3 phosphate that is called a "high energy bond" when this bond is broken, energy is released.
ADP, Adenosine Diphosphate only has 2 phosphate groups and lacks the high energy bond between the 2nd and 3rd phosphate group. ADP is the product of ATP dephosphorylation by ATPases (ATPases are enzymes that dephosphorylize ATP by removing a phosphate). And likewise ADP is converted back to ATP by ATP synthases. These enzymes add a phosphate group in a process called phosphorylation.
I hope this helps! Best of Luck!

ATP has 3 phospate bonds and ADP has only 2.
Energy is released by breaking these bonds so ATP produces more energy.

ATP, because it has 3 phosphate groups, which means it has more energy stored.
