Respiration
- Respiration is a chemical reaction carried out in all living organisms
- Energy is released from glucose either in the presence of oxygen (aerobic respiration) or the absence of oxygen (anaerobic respiration)
- The reactions ultimately result in the production of carbon dioxide and water as waste products
- Energy is transferred in the form of ATP
The equation for aerobic respiration
Exam Tip
Make sure not to confuse respiration with gas exchange. Gas exchange involves getting oxygen into the cells and carbon dioxide out. Respiration uses the oxygen supplied from gas exchange to release energy in the form of ATP.
