Its easy. Its respiration.
that is called metabolism
The release of Energy
ATP
Sugar is broken down with water to produce carbon dioxide. It is accompanied by release of chemical energy. This process is also termed respiration and is used in breathing process by animals.
Cellular respiration
cellular respiration
cellular respiration
Neither, the process of burning gas (which stores chemical energy) releases that energy as "HEAT" energy. This heat energy is then converted into mechanical energy.
The opposite of cellular respiration (oxidation) would be photosynthesis, the process plants use to create carbohydrates, which contain chemical bonds that can be broken to release energy.
Glucose is broken down IN cellular respiration, also called the Kreb cycle. Glucose enters this electron transport chain process intact, and is broken down to CO2 and water, while giving off chemical energy which is stored in the form of ATP molecules for the cell to use for chemical energy in metabolic processes. Glucose is not broken down before cellular respiration; it is broken down IN the process.
chemical energy is energy found in substances. energy is never lost or gained (remember that) . you can measure the energy and release energy by heating substances. This way energy is released when the compounds heated are broken down.
