In case of prokaryotic organisms such as bacteria and archaebacteria, other types of respiration occur.
Carbon dioxide is also a product of cellular respiration which is released as a waste product.
There are three major types of cellular respiration occur such as aerobic, lactic acid fermentation, alcoholic fermentation.
In aerobic respiration 36 ATP, where as in lactic acid fermentation 2 ATP and alcoholic fermentation 2 ATP are produced.
