Question

Explain the ways in which gluecose is broken down in absense of oxygen.

Answer 1

If oxygen is present, then glucose can be broken all the way down into carbon dioxide and water. This process is called aerobic respiration because it requires air (oxygen). In the absence of oxygen, the cell uses a process called anaerobic fermentation. or simply fermentation. Fermentation doesn't break the sugar down any further, it simply helps reset the system so that more sugar can be broken down.

Because aerobic respiration breaks the sugar all the way down, it releases much more energy than fermentation.
