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 and Coupled Reactions. Many reactions in cells are endothermic (require energy), such as protein synthesis. The energy comes from the breakdown of ATP (adenosine triphosphate); this process provides energy and so is exothermic. When the energy released by an exothermic reaction drives an endothermic reaction these two reactions are said to be a coupled reaction. What is ATP (Adenosine triphosphate)? The ATP Cycle. How do we get energy from ATP? How much energy do we get from one ATP molecule? Every time ATP is broken down into ADP, 31 kJ/mol of energy is released.
