Respiration and Metabolism

• respiration is the process of transferring energy from the breakdown of glucose which transfers to every cell.
• respiration is exothermic. it transfers energy to its surroundings
• How organisms use the energy transferred by respiration:

  • to build up larger molecules from smaller ones
  • allows muscles to contract, so they can move about
  • in mammals and birds the energy is used to keep their body temperature steady in colder surroundings
