Anaerobic respiration takes place in the absence of oxygen. Unlike aerobic respiration the
NADH is oxidised by fermentation, a process in which no more ATP molecules are generated.
Fermentation; in the absence of oxygen, the pyruvate
generated by glycolysis can follow one of two metabloic
pathways; alcoholic fermentation, lactate fermentation
Alcoholic fermentation; occurs in plants
and yeast that are expiring anaeorbically
Glucose (6C)
2 pyruvate (3C)
2 Ethanol (2C)
2 CO2
Glycolysis
Glycolysis
Lactate fermentation; occurs in
animals that are respiring anaerobically
