What is aerobic respiration?
Important enzyme-controlled processes in living things.
Provides energy.
What is the word equation for aerobic respiration?
glucose+oxygen->carbon dioxide+water
+energy
Why do mitochondria have folded inner membranes?
Provides a large surface area for the enzymes involved in aerobic respiration.
3 reasons for respiration:
- living cells need it to carry out basic functions of life
- used to make muscles contract
- keep their bodies at a constant temperature
Why is aerobic respiration so important?
Releases energy that your cells can use which is vital for everything that goes on in your body.
Why do we produce more CO2 when we exercise hard?
- heart rate increases which increase the blood flow to the muscles and increases the supply of oxygen and glucose to the muscles and the rate that CO2 is removed.
- breathing rate increases so more oxygen is brought into the body and picked up your red blood cells
What are some benefits of exercising?
- heart and lungs become larger
- bigger and more efficient blood supply
How does anaerobic respiration differ from aerobic respiration?
Aerobic respiration uses oxygen.
Anaerobic respiration doesn’t use oxygen.
What happens in aerobic respiration?
Glucose isn’t broken down completely so produces lactic acid instead of carbon dioxide and water.
Name a cause of muscle fatigue:
Build up of lactic acid.
What removes lactic acid?
Blood flowing through the muscles.
