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.
Before ATP can release energy it has to be produced. ATP production is a chemical process formed from a reaction between adenosine diphosphate and inorganic phosphate. The result is the formation of ATP and water. The reaction itself requires significant amounts of energy (which is of the order of 7.3 kcal/mole) and the process takes place through various modes such as glycolysis, photosynthesis and cellular respiration.
