Respiration
Contents
Key Stage 2
Meaning
Respiration is the process of getting energy from food.
Key Stage 3
Meaning
Respiration is the process of releasing energy from food molecules.
About Respiration
- Respiration may be Aerobic Respiration, requiring Oxygen, or Anaerobic Respiration which can take place in the absence of Oxygen.

 |
| The word equation for aerobic respiration showing the reactants and products. | A word equation for anaerobic respiration in animal cells, plant cells and bacteria showing the reactants and products. |
Key Stage 4
Meaning
Respiration is the process of releasing energy from food molecules.
About Respiration
- Respiration may be Aerobic Respiration, requiring Oxygen, or Anaerobic Respiration which can take place in the absence of Oxygen.
Aerobic Respiration: Glucose + Oxygen → Water + Carbon Dioxide
Anaerobic Respiration: (in humans): Glucose → Lactic Acid
Anaerobic Respiration: (in yeast): Glucose → Ethanol + Carbon Dioxide
- In eukaryotic cells respiration takes place in the mitochondria.
- In prokaryotic cells respiration takes place in the cytoplasm of the cell.
