Aerobic and Anaerobic Respiration
Biology: Cambridge International GCSE Supplement, topic 12.2.3
Aerobic and Anaerobic Respiration
There are key differences between aerobic and anaerobic respiration:
ATP
- Aerobic respiration produces much more adenosine triphosphate (ATP, which is a unit of energy) than anaerobic respiration.
Products
- Aerobic respiration produces carbon dioxide and water.
- Anaerobic respiration produces carbon dioxide and ethanol (plants and yeast) or lactic acid (animals).
Oxygen
- Oxygen is need for aerobic but not anaerobic respiration.
Glucose
- Aerobic respiration fully breaks down glucose.
- Anaerobic respiration only partially breaks down glucose.
