Fermentation is an important process that allows organisms growing in anaerobic environments to harvest energy from glucose. Which statement about fermentation explains one other reason why fermentation is important to anaerobic organisms?
a. The amount of energy harvested from a molecule of glucose using fermentation is much less than the amount harvested using aerobic respiration.
b. Fermentation and aerobic respiration share the steps that involve oxidation of glucose to pyruvate.
c. Different enzymes are used in alcoholic and lactic acid fermentation to metabolize pyruvate at the final step.
d. Fermentation provides a means for the cycling of NADH back to NAD+ so that glycolysis can continue.
e. Most organisms that rely on fermentation are small microbes that grow relatively slowly.
