Different celestial objects produce different types of spectra. The spectrum of an object is one means of identifying what type of object it is. How different spectra arise is shown in the schematic diagram below.
After a simple reaction breaking down ATP to ADP, the energy released from the breaking of a molecular bond is the energy we use to keep ourselves alive. When the phosphate group is removed. After a simple reaction breaking down ATP to ADP, the energy released from the breaking of a molecular bond is the energy we use to keep ourselves alive.
ATP is at a high level of chemical potential but the type of energy released from its hydrolysis depends on the application. The short answer is that the hydrolysis of ATP to ADP always releases heat, and if coupled with a cellular process it additionally produces either chemical potential (in another species) or work. Let me back up a bit, and note that ATP is a species that has a high degree of potential energy.
