                         1.4  Respiration





                       In this topic you will:
                       •    find out how every living cell gets the energy it needs

                            to stay alive
                       •    do an experiment to investigate how, in respiration, some
                            energy is released as heat

                       •    think about the difference between breathing and
                            respiration.




                       Getting started                                                             Key words

                       Think back to Stage 7, when you learned about energy.                       glucose
                       With a partner, think about this question:                                  mitochondria

                       What has to happen to energy, in order to make something
                       happen?
                       Can you give some examples?
                       Be ready to share your ideas.
