Answer:
The correct answer is option c. "The basic function of fermentation is the regeneration of NAD , which allows continued ATP production by glycolysis".
Explanation:
For bacteria, the basic function of fermentation is not the production of ATP or ethyl alcohol, the basic function of fermentation is the regeneration of NAD+ , which allows continued ATP production by glycolysis. Bacteria normally uses glycolysis for ATP production, it only undergoes fermentation in the absence of oxygen. During bacterial fermentation, a small organic compound as an electron acceptor is used for NADH and regenerates NAD+, this NAD+ is later used in glycolysis for ATP production.
