Question:
(a) What is the difference between fermentation and glycolysis? (b) Why do cells rely on fermentation rather than glycolysis alone?
Author: fahr datAnswer:
(a) The major difference between fermentation and glycolysis is that the fermentation pathway includes additional reactions needed to regenerate the NAD+ that was reduced during glycolysis. (b) If cells relied on glycolysis alone, they would quickly run out of NAD+, a necessary reactant in glycolysis. They rely on fermentation to regenerate the NAD+.
