All living creatures need to breathe and respire. The arctic fox cannot survive without the respiratory system as it needs it to get oxygen into its body and to release carbon dioxide. The main organs in the respiratory system are:
There are two main types of respiration, aerobic and anaerobic. Aerobic respiration is what happens I there’s plenty of oxygen available. Aerobic means “with oxygen” and it’s the ideal way to convert glucose into energy.
- Lungs
- Heart
- Diaphragm
- Trachea
There are two main types of respiration, aerobic and anaerobic. Aerobic respiration is what happens I there’s plenty of oxygen available. Aerobic means “with oxygen” and it’s the ideal way to convert glucose into energy.
The word equation:
Glucose + Oxygen → Carbon Dioxide + Water + Energy
… and the chemical equation:
C₆H₁₂O₆ + 6O₂ 6CO₂ + 6H₂O + Energy
The word equation for anaerobic respiration is:
Glucose → Ethanol + Carbon Dioxide + Energy
Anaerobic respiration is what happened when there is no oxygen available. Anaerobic means “without oxygen”. It’s the incomplete breakdown of glucose which is not the best way to convert glucose into energy because it produces lactic acid. Lactic acid builds up in the muscle and it gets very painful. When you do vigorous exercise, your body is unable to supply enough oxygen to your muscles and starts performing anaerobic respiration instead. The advantage is that you are able to use your muscles for a while longer. When you stop, you’ll have an oxygen debt. This is when you have to “repay” the oxygen that you didn’t get to your muscles in time, because your organs couldn’t keep up with the demand earlier on. This is means that you have to keep breathing harshly for a while after you stop to get oxygen into your muscles to oxidise the painful lactic acid to harmless CO₂ and water.
