Which of the following is true regarding fermentation?
Group of answer choices
Fermentation occurs in the cell membrane of organisms
Yeast produces lactic acid through fermentation
At the end of fermentation NADH is converted back into NAD+
The end product pyruvate proceeds into the Krebs cycle
Homework Answers
Option c, at the end of the fermentation NADH is converted back to NAD+ .
Fermentation occurs in cytoplasm, not in cell membrane
In Yeast fermentation is alcoholic fermentation not lactic acid fermentation.
In fermentation pyruvate converted in to either lactate or alcohol not enter in to TCA.

We have discussed fermentation as a mechanism for regeneration of NAD for glycolysis under conditions when an ETC is not available for NAD regeneration. Embden-Meyerhof glycolysis converts one NAD to NADH for each molecule of pyruvate produced. Fermentation of pyruvate to propionic acid converts one NADH to NAD for each molecule of pyruvate fermented. Which of the following statements is TRUE of metabolism under conditions that force the use of pyruvate fermentation to propionate? It should be possible to perform...
