Lesson Details
Key learning points
- In microorganisms, anaerobic cellular respiration produces carbon dioxide and a type of alcohol called ethanol.
- A word summary of the reactants and products of anaerobic cellular respiration in microorganisms.
- Anaerobic cellular respiration in microorganisms is also called fermentation.
- Humans use fermentation in microorganisms to make useful products such as bread, yogurt and alcoholic drinks.
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.
