Concept 5:Fermentation
All cells are able to synthesize
ATP via the process of glycolysis. In many cells, if oxygen is not
present, pyruvate is metabolized in a process called fermentation.
Fermentation complements glycolysis and makes it possible for ATP to
be continually produced in the absence of oxygen. By oxidizing the
NADH produced in glycolysis, fermentation regenerates NAD+, which
can take part in glycolysis once again to produce more ATP.
