Question

identify all correct statements about the basic function of fermentation.
select all that apply.
the basic function of fermentation is the production of ethyl alcohol or lactic acid.
the basic function of fermentation is the production of additional atp by further oxidation of the products of glycolysis.
the basic function of fermentation is the regeneration of nad+, which allows continued atp production by glycolysis.

Explanation:

Fermentation occurs in the absence of oxygen. Glycolysis produces \(NADH\). To keep glycolysis going (as glycolysis needs \(NAD^{+}\)), fermentation regenerates \(NAD^{+}\) from \(NADH\). Ethyl alcohol or lactic acid are just by - products. Fermentation does not produce additional ATP by further oxidation of glycolysis products (that would be aerobic respiration).

Answer:

The basic function of fermentation is the regeneration of \(NAD^{+}\), which allows continued ATP production by glycolysis.
