Lesson Details
Key learning points
- Anaerobic cellular respiration takes place without using oxygen.
- In humans, anaerobic cellular respiration produces lactic acid, which can cause muscle cramps.
- Word summaries of the reactants and products of aerobic and anaerobic cellular respiration in humans.
- Anaerobic cellular respiration takes place only in the cytoplasm of cells and does not involve the mitochondria.
- Anaerobic cellular respiration provides less energy than aerobic cellular respiration, but provides energy more quickly.
Common misconception
Learners often assume there is only one type of cellular respiration (aerobic).
This lesson explores aerobic and anaerobic cellular respiration in humans.
Keywords
Anaerobic cellular respiration - Anaerobic cellular respiration is a type of cellular respiration that does not use oxygen and takes place in the cytoplasm of cells.
Lactic acid - Lactic acid is a product of anaerobic cellular respiration in humans which causes muscle cramps.
Cytoplasm - The cytoplasm is the jelly-like substance inside a cell where chemical reactions of the cell take place.
Aerobic cellular respiration - Aerobic cellular respiration is a type of respiration that requires oxygen and takes place in the mitochondria and cytoplasm of cells.
