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.
Despite common misconception, energy is NOT released when you break the phosphate bond for ATP. Energy must be put in to break the bond. However, the bonds that are formed in the products release more energy overall, thus gives rise to the idea that ATP releases energy when it turns to ADP.
