A high energy molecule is made from adenosine with phosphates. The most well-known example is adenosine triphosphate (ATP), which is the primary energy currency of cells.

Here's a breakdown:

* Adenosine: This is a nucleoside composed of adenine (a nitrogenous base) and ribose (a sugar).

* Phosphates: These are negatively charged molecules attached to the adenosine. ATP has three phosphate groups.

The bonds between the phosphate groups in ATP store a significant amount of energy. When these bonds are broken, energy is released, which can be used to power cellular processes.
