Why is it beneficial for pyruvate to be reduced via fermentation when oxygen is not available?
A)The organism can survive short spells of anaerobic conditions and maintain growth and reproduction.
B)The fermentation reaction regenerates NAD+,which is required for the first step in the energy-harvesting phase of glycolysis.
C)Fermentation can provide a rapid burst of ATP.
D)All of the choices are advantages.
E)None of the choices is an advantage.
