Fermentation is an anaerobic response for yeast. Yeast will respire aerobically in the presence of oxygen and will not produce alcohol.
Fermentation
Fermentation normally occurs in an the absence of oxygen (called anaerobic) but is can occur in its presence
anaerobic (e.g. fermentation)
Anerobic respiration
Anaerobic means "without air (oxygen)". Fermentation allows some cells to make ATP without having oxygen present. Fermentation is not nearly as efficient as aerobic respiration, since it produces a net yield of only 2 ATP per glucose molecule (aerobic respiration produces 36-38 ATP per glucose).
fermentation results in evolution of carbondioxide. fermentation can be carried out either aerobically(in presence of oxygen or air) or anaerobically(in absence of oxygen).
Fermentation
Respiration uses oxygen, fermentation doesn't.
Respiration uses oxygen, while fermentation does not use oxygen.
For fermentation to take place, oxygen needs to be completely absent. The word anaerobic means without oxygen. So the missing thing that makes fermentation anaerobic is oxygen.
The breakdown of food without the use of oxygen is fermentation.
Basically Fermentation is an Anaerobic respiration (i.e. Oxidation of energy compounds in the absence of oxygen).That means the answer to your question is 'oxygen'.
Fermentation normally occurs in an the absence of oxygen (called anaerobic) but is can occur in its presence
one uses oxygen to get energy and the other uses yeast!Fermentation does not need oxygen. Aerobic respiration need oxygen
Fermentation occurs in the Cytosol (cytoplasm), without oxygen.
