Biology
Respiration - Anaerobic
- Anaerobic respiration is the incomplete breakdown of glucose and produces lactic acid
- Anaerobic respiration takes place in animal, plant and some microbial cells in
conditions of low oxygen or absence of oxygen, such as: 1) plant roots in waterlogged
soil 2) bacteria in puncture wounds 3) human cells during vigorous cells
- Anaerobic respiration releases less energy per glucose molecule than aerobic
respiration because glucose is only partially broken down
...
- 2) The anaerobic respiration produces lactic acid which accumulates in the muscles
...
- 4) The build-up of lactic acid requires extra oxygen to break it down

- This can be
called fermentation, used to make alcoholic drinks and to make bread
(CO2) as the carbon dioxide causes the dough to rise

A lot of oxygen is needed so we breathe
deeper and faster to get oxygen into the blood, the heart beats faster to get the
oxygen round the body to the muscle cells

extra energy comes from anaerobic respiration

It is a mild poison that needs to be broken down by combining it
with oxygen
...
Whilst exercising we built up an oxygen debt,
once the lactic acid combines with oxygen you’re paying off the debt
