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.
