Question

in the presence of yeast glucose convert in to alcohol how it is separated

Answer 1

Carbon dioxide (CO₂) gas released during fermentation process.

During fermentation process yeast kills itself by converting the sugars (C₁₂H₂₂O₁₁) found in grapes to ethyl alcohol. Alcohol can be separated from this mixture of yeast and other formed products by distillation process.

Products  formed during  fermentation

C₁₂H₂₂O₁₁ + H₂O + (invertase) → C₆H₁₂O₆ (glucose) + C₆H₁₂O₆ (fructose)

C₆H₁₂O₆ (glucose)  + Zymase →2 C₂HOH (ethyl alcohol) + 2CO₂
