Summary Respiration notes or OCR biology A level

, RESPIRATION
All living organisms need energy for biological
processes
. Energy is stored in organic molecules
(glucose) The energy in these molecules is
released during respiration
. This is used to

synthesise ATP which is then used wi
reactions such as ATP .




Respiration also energy helping produces heat ,
