What fermentation products are made by both yeast and humans?
Which product of fermentation is made by both humans and yeast?
a. Ethanol
b. CO2
c. NAD+
d. NADH

In humans, lactic acid fermentation happens resulting in lactate, while the product of yeast fermentation is ethanol. For both, there is a regeneration of NAD+...so my guess is C. But if you take a "hangover" and Auto-Brewery syndrome, don't both yeast and humans both make ethanol as well?

So, I'm torn between C and E. Anyone care to help?
