Cellular respiration results in the formation of ATP molecules. ATP, or adenosine triphosphate, is often called the “unit of currency” for energy transfer. Glucose can be thought of as a molecule that stores energy. ATP, on the other hand, is a molecule that transports energy. When cells need energy, it is converted from “storage” into the form of ATP. Each molecule of ATP contains a chain of three structures called phosphates. When the third phosphate is released, the ATP becomes ADP (adenosine diphosphate). Breaking that bond releases energy.
