Here's why:

* High-energy bonds in ATP are broken, not formed, when hydrolyzed. Hydrolysis is the process of breaking a bond using water.

* Energy is released, not absorbed, when ATP is hydrolyzed. This energy release is what powers many cellular processes.

Here's the correct breakdown:

* ATP (adenosine triphosphate) has three phosphate groups. The bonds between these phosphate groups are called high-energy bonds.

* Hydrolysis of ATP breaks one of these high-energy bonds. This results in:

* ADP (adenosine diphosphate) - which now has two phosphate groups.

* One free phosphate group.

* The energy stored in the broken bond is released. This energy is then used to drive various cellular processes.

Think of it like this: ATP is like a charged battery. When you hydrolyze it, you're "discharging" the battery, releasing the stored energy.
