respiration

• Respiration is the process of transferring energy from glucose which goes on in every cell.
• Respiration involves many reactions. These are really important as respiration transfers the energy that the cell needs to do for everything. This energy is used for all living processes.
• Respiration is exothermic
• examples of how organisms use the energy provided by respiration:

  • to build up larger molecules from smaller ones
  • in animals, it is used to allow the muscles to contract
  • in mammals and birds, the energy is used to keep their body temperature steady in colder surroundings
