Aerobic Respiration vs
...
It happens in every cell of every biotic organism - all the time
...
Glucose can be used by cells to respire, but other organic molecules can be used
as substrates such as proteins, lipids, and carbohydrates
...
This also means that respiration is affected by temperature and pH
...
Aerobic Respiration
Simply put, ‘Aerobic’ means ‘with plenty of oxygen’
...
It produces 32 molecules of ATP
per molecule of glucose – which is a lot compared to anaerobic
...
It is not as efficient as aerobic respiration
(only producing 2 molecules of ATP for every molecule of glucose)
...
Anaerobic respiration occurs differently within different organisms
...
The glucose is
only partially broken down, and lactic acid is also produced
...
You can still use your
muscles though
...
An oxygen debt is the amount of oxygen needed to get rid of the
lactic acid that has built up and to help anaerobic respiration to begin again
...
The word equation for this
is:
Glucose → Lactic Acid + Energy Released
- Plants and Fungi produce Ethanol and Carbon Dioxide
...
Some fungi –
like yeast – also respite anaerobically too
...
The word
equation for this is :
Glucose → Ethanol + Carbon Dioxide + Energy Released
Key Differences
Aerobic Respiration
Anaerobic Respiration
- Has plenty of oxygen
- The glucose fully breaks down
- Produces lots of ATP
- Gases are exchanged
- Not enough oxygen
- The glucose is only partially broken
down
- Produces little ATP
- Gases are not exchanged
Glossary
- Enzyme – A biological catalyst produced by a living organism to help a
certain biochemical reaction
...
- ATP – (Adenine Triphosphate) carries energy within cells
...
- Proteins - Big molecules made of one or more chains of amino acids
...
- Carbohydrates - A carbohydrate is a biomolecule consisting of carbon,
hydrogen and oxygen atoms
...
- pH – The pH scale is a scale used to determine the acidity or basicity of a
solution
