Metabolism Problem Set
Problem 11: Fermentation
In the absence of oxygen, the primary purpose of fermentation is to:
A. produce amino acids for protein synthesis
B. generate a proton gradient for ATP synthesis
C. oxidize glucose to generate reduce electron carriers
D. generate alcohol for beverages
regenerate NAD+ from NADH allowing glycolysis to continue
Fermentation allows continued glycolysis by regenerating NAD+ from NADH. NAD+ is limiting, and must be reformed to allow the continuation of the glycolytic degradation of glucose producing ATP.
