Respiration is a process which releases energy from energy-rich molecules such as glucose. The glucose is converted into energy which is usable for life processes. Burning, or combustion, is a reaction between a substance and a gas to release energy. These two reactions have many similarities but are not the same. This essay will identify some of similarities and differences between the two processes. The first similarity is that both respiration and burning use oxidation …

…the energy from burning can not be stored. The energy released from respiration is used to join a phosphate group onto an ADP molecule, making a new molecule called ATP. <Tab/>ADP + phosphate + energy → ATP ADP has low energy content while ATP has high energy content, so ATP can be broken down again to release energy when body needs energy. <Tab/>ATP → ADP + phosphate + energy
