In anaerobic respiration, which byproducts are commonly produced?

Explanation:
When oxygen isn’t available, cells must regenerate NAD+ after glycolysis to keep producing ATP. Fermentation does this by transferring electrons from NADH to pyruvate or its derivatives. In animals, pyruvate is reduced to lactate, which regenerates NAD+ and allows glycolysis to continue. In yeast (and some bacteria), pyruvate is converted to ethanol (via acetaldehyde), releasing CO2 along the way; ethanol buildup is the main byproduct here. So the common byproducts of anaerobic respiration are lactate or ethanol. Oxygen isn’t produced, chlorophyll isn’t involved, and glucose is the starting material, not a byproduct.
