Question

What gas is used to break apart sugar during respiration?

  1. Oxygen
  2. Carbon dioxide
  3. Nitrogen
  4. Argon

hintHint:

The gas that we inhale during breathing.

The correct answer is: Oxygen


    Oxygen
    • The oxygen we inhale is used to breakdown glucose into carbon dioxide and water.
    • Energy is released in the process.

    • Oxygen is used to breakdown glucose into carbon dioxide and water.
    • The breakdown of glucose occurs in the cells of an organism.

    What is one of the ‘ingredients’ for photosynthesis?

    • Within the plant cell, the water is oxidised, means loses electrons. And carbon dioxide is reduced, means it gains electrons.
    • This transforms, the water into oxygen and carbon dioxide into glucose.
