When an ATP molecule is activated or used, what are the resulting molecules?

(sounds unfinished but thats a full question that's on my study guide ...)

All living things require energy to function. While different organisms acquire this energy in different ways, they store (and use it) in the same way. In this section, we'll learn about ATP-the energy of life. ATP is how cells store energy. These storage molecules are produced in the mitochondria, tiny organelles found in eukaryotic cells sometimes called the "powerhouse" of the cell.
