What is the primary reason for the evolution of fermentation in eukaryotic cells?
A.A) To produce more ATP
B.B) To regenerate NAD+
C.C) To produce ethanol and lactic acid
D.D) To reduce oxygen consumption
Explanation
Core Concept
The primary reason for the evolution of fermentation in eukaryotic cells is to regenerate NAD+ for glycolysis. During glycolysis, NAD+ is reduced to NADH, which must be reoxidized for the process to continue. Fermentation allows for the reoxidation of NADH, thereby regenerating it for continued glycolysis.
