Chemical
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
Chemical compounds.
Chemical compounds.
All substances can be broken into any other substances (or elements) by chemical or physical methods.
glucose is broken down by cellular respiration
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.
respiration
oxygen and nutrients/food are taken in, and carbon dioxide and waste are transferred out. The main chemical is energy which is released from cellular respiration.
