RESPIRATION ID THE PROCESS OF RELEASING ENERGY FROM GLUCOSE, WHICH HAPPENS CONSTANTLY IN EVERY CELL
glucose is used to build up larger molcules (like proteins), contract muscles and maintain a steady body temperature
Anaerobic & Aerobic respiration
Aerobic - Happens when there is plenty of oxygen available, releases more energy per glucose molecule.
- used most of the time
glucose + oxygen ----> carbon dioxide + water (+ energy released)
Anarobic - doesnt use oxygen
- releases much less energy
