Respiration

  • Cellular respiration is an exothermic reaction that happens continuously in every living cell. The energy it transfers supplies all the energy needed for living processes
  • Organisms need energy for chemical reactions to build larger molecules, for movement, and for keeping warm
  • It can be aerobic (using oxygen) or anaerobic (without oxygen)
