Lesson details

Key learning points

  1. In microorganisms, anaerobic cellular respiration produces carbon dioxide and a type of alcohol called ethanol.
  2. A word summary of the reactants and products of anaerobic cellular respiration in microorganisms.
  3. Anaerobic cellular respiration in microorganisms is also called fermentation.
  4. Humans use fermentation in microorganisms to make useful products such as bread, yogurt and alcoholic drinks.

Keywords

  • Microorganism - A microorganism is a living organism made up of one or a small number of cells.

  • Anaerobic cellular respiration - Anaerobic cellular respiration is a form of cellular respiration which occurs without oxygen.

  • Ethanol - Ethanol is a product of anaerobic cellular respiration in microorganisms.

  • Alcohol - Alcohols are a group of compounds containing carbon, hydrogen and oxygen.

  • Fermentation - The process of anaerobic respiration in microorganisms is called fermentation.

Common misconception

Students can often confuse the word summaries for the different types of cellular respiration.

This lesson directly compares the different word summaries for anaerobic cellular respiration to help understand the differences between them.

Task B is an experiment which students could carry out themselves.
