why would an organism with repiratory equipment ever resort to fermentation???
i don't understand how respiratory is related to fermentation :[

In certain cases the muscles need to produce energy at a faster rate than under normal conditions. Since the respiratory system cannot supply enough oxygen during a strenuous athletic event like running a half mile or 100 yard dash. The muscles undergo the anaerobic process called fermentation to produce the energy needed for a short time without oxygen. They produce lactic acid which is later converted back to glucose after the strenuous event. It is a reserve process that is retained to help in situations like the ones mentioned.

These cells use fermentation when there is no oxygen available for cellular respiration. Otherwise, they use respiration.
After glycolysis, there are two possible pathways. If oxygen is present, then the cells follow the pathway that is cellular respiration. If no oxygen is present, then the cells follow the pathway that is fermentation. They have to do one or the other or glycolysis will stop. So that's how they are related.

Because fermentation doesn't require oxygen, an organism can do it if it's running out of air.
