Question

In the conversion of pyruvate to ethanol,what is produced?  
A) Acetaldehyde only
B) Carbon dioxide only
C) NADH only
D) Acetaldehyde and carbon dioxide
E) Acetaldehyde, carbon dioxide, and NADH

Accepted Answer

In the conversion of pyruvate to ethanol, acetaldehyde and carbon dioxide are produced as the end products. This process is called alcoholic fermentation and is used by some organisms, such as yeast, to generate energy in the absence of oxygen. NADH is also produced as a byproduct, but it is not the only product.
