4. When breakdown of glucose occur with
presence of oxygen it is called aerobic
respiration
In aerobic respiration large amount of
energy is released
Example of aerobic respiration – human
beings
It releases water and carbon dioxide
5. ANAEROBIC RESPIRATION
When breakdown of glucose occur
without the presence of oxygen it
is called anaerobic respiration
It releases less amount of energy
Example of anaerobic respiration –
yeast
It releases alcohol and carbon
dioxide
6. Our body muscles also respire anaerobically.
During heavy exercise demand of energy is very so
but supply of oxygen is limited . In this case anaerobic
respiration takes place
Glucose Absence of O2 Lactic acid Energy
