The products of fermentation of sugar are

The correct answer is "ethanol and carbon (IV) oxide". Fermentation is a metabolic process that converts sugar (glucose) into alcohol (ethanol) and carbon dioxide through the action of enzymes in the absence of oxygen. The reaction is catalyzed by yeast or bacteria, which break down the glucose molecule into two molecules of pyruvate in a process called glycolysis. Pyruvate then undergoes further chemical reactions that produce ethanol and carbon dioxide as waste products. The balanced chemical equation for the fermentation of glucose is: C₆H₁₂O₆ → 2 C₂H₅OH + 2 CO₂ So, the products of fermentation of sugar are ethanol and carbon dioxide.
