Anaerobic respiration: Topic 16: Biology:
Anaerobic respiration is the release of energy from glucose without the use
of oxygen, opposite of aerobic
...
It is used when there is not
enough oxygen for aerobic respiration
...
This also takes place in plants and some microbial cells in
the presence of little or no oxygen
...
Glucose = lactic acid
(+energy)
Anaerobic respiration is not as efficient as aerobic as it occurs when vigorous
exercise is carried out
...
Only a little amount of energy is
released because the glucose is partially broken down so it is not able to produce
enough
...
This builds up in the body and stops the muscles from working
causing cramps
...
The required oxygen, needed for the prevention of this
chemical ‘side-effect’ is referred to as oxygen debt
...
Anaerobic is still present while the anaerobic process in continuing, it’s just
anaerobic releases that extra energy the cell is in need of but can’t get from aerobic
...
Advantages
Anaerobic is useful as it provides that
extra energy the cell need in order to
cooperate with the aerobic system, when
the lungs and heart are unable to deliver
the glucose and oxygen to give the
muscles the energy to work
...
Lactic acid is not removable,
nevertheless it finally gets broken down
after the exercise has finished
...
Anaerobic releases too little energy from
each molecule of glucose than aerobic
...
P
...
C -AKA- Excess post-exercise oxygen consumption
When someone exercises hard they will realise their heart and breathing rate
will take a while to return to normal after the vigorous movement
...
EPOC is really the amount of oxygen required after the exercise has ended
compared with the resting rate
...
This is
because glucose is not broken down completely to form carbon dioxide and
water
...
The heart rate and breathing rate continuously remain high after exercise to
bring extra oxygen into the body
...
Blood pressure is measured in millimetres of mercury, mmHg
...
Diastolic pressure - the lower measurement when the heart rests
between beats
...
Blood pressure varies with age
