Which of the following accurately describes fermentation? A. All types of fermentation produce carbon dioxide. B. Fermentation can only occur in the presence of oxygen. C. Fermentation makes NAD + needed to keep glycolysis going. D. Fermentation generates more ATP than cellular respiration.

The correct answer is C. Fermentation makes NAD + needed to keep glycolysis going. The other options are inaccruate since:

for A: there are types of fermentation that does not produce carbon dioxide like Lactic acid fermentation

for B: many types of fermentation only occurs in the absence of oxygen (anaerobic process)

for B: respiration produces around 36 ATP while fermentation only generates around 2 ATP
