In the production of ethanol by fermentation, why is the process done in the absence of air?If air were present the alcohol would oxidise to make an esterIf air were present the yeast would not be able to survive as they can only respire anaerobicallyIf air were present the yeast would respire aerobically, producing carbon dioxide and water, instead of ethanolIf air were present the ethanol produced would be impure because it would have gases from the air dissolved in itQuestion 7 of 14 Loading... 8.
