Lactate Fermentation Transfers the Electrons and Hydrogen Ions Carried by NADH

Question

Lactate fermentation transfers the electrons and hydrogen ions carried by NADH directly to ____.  
A) acetaldehyde
B) pyruvate
C) carbon dioxide
D) oxygen
E) myoglobin

Accepted Answer

During lactate fermentation, NADH donates its electrons and hydrogen ions directly to pyruvate, forming lactate as the end product. This allows for the regeneration of NAD+ so that glycolysis can continue in the absence of oxygen. The other options are not involved in lactate fermentation.
