Lesson details

Key learning points

  1. Aerobic cellular respiration requires oxygen.
  2. The reactants and products of aerobic cellular respiration can be summarised using a word equation.
  3. Aerobic cellular respiration takes place in the mitochondria and cytoplasm of animal, plant and fungi cells.
  4. Cells that require more energy, because they do a lot of work, have more mitochondria.

Keywords

  • Aerobic cellular respiration - Aerobic cellular respiration is a chemical process that uses oxygen from the air and glucose to provide energy for life processes.

  • Oxygen - Oxygen is an element found in the air that is a gas at room temperature and a reactant in aerobic cellular respiration.

  • Carbon dioxide - Carbon dioxide is a compound made of carbon and oxygen that is a gas at room temperature and a product of aerobic cellular respiration.

  • Mitochondria - Mitochondria are subcellular structures that use glucose and oxygen to carry out aerobic cellular respiration.

  • Cytoplasm - Cytoplasm is the jelly-like substance inside a cell where its chemical reactions take place.

Common misconception

Aerobic cellular respiration is a single chemical reaction.

This lesson uses the terms 'chemical process' and 'series of chemical reactions'.

Say 'aerobic cellular respiration provides energy for life processes' rather than 'releases energy', as 'releases' can lead to pupils having incorrect ideas about energy.
