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

That is true it is called an aftershock
