Aerobic and Anaerobic
Biology: Edexcel IGCSE, topic 3.1.2
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 needed for aerobic but not anaerobic respiration.

Glucose
- Aerobic respiration fully breaks down glucose.
- Anaerobic respiration only partially breaks down glucose.
