A hungry yeast cell lands in a vat of grape juice andbegins to feast on the sugars there, producing carbon dioxide andethanol in the process:C6H12O6 + 2ADP + 2Pi + H + - --> 2CO2 + 2CH3CH2OH + 2 ATP + 2H2OUnfortunately, the grape juice is contaminated withproteases (enzymes that attack some fo the transport proteins inthe yeast cell membrane), and the yeast cell dies. Which ofthe following could account for the yeast cell'sdemise? a) toxic buildup of carbon dioxide inside thecellb) toxic buildup of ethanol inside thecellc) diffusion of ATP out of the celld) inability to import sugar into thecelle) inability to take water into thecell
