Respiration
Aerobic
- Needs oxygen!
- glucose + oxygen > carbon dioxide and water
- Happens all the time in plants and animals.
- Most reactions in aerobic respiration happen inside the mitochondria of a cell.
- Releases large amounts of energy in cells by the breakdown of food substances.
Anaerobic
- DOESN'T need oxygen!
- Releases small amounts of energy in cells by the breakdown of food substances
- Happens in muscles during hard exercise: glucose > lactic acid
- Glucose isn't completely broken down so less energy is released.
- Build-up of lactic acid = oxidised to CO2 and water later
- This causes 'oxygen debt' which has to be repaid later. This is why we keep breathing deeply after exercise.
