Question

A hungry yeast cell lands in a vat of grape juice and begins to feast on the sugars there, producing carbon dioxide and ethanol in the process:

C6H12O6 + 2 ADP + 2 Pi + H+ <--> 2 CO2 + 2 CH3CH2OH + 2 ATP + 2 H2O

Unfortunately, the grape juice is contaminated with proteases that attack some of the transport proteins in the yeast cell membrane, and the yeast cell dies. Which of the following could account for the yeast cell’s demise?

inability to import sugar into the cell

toxic buildup of ethanol inside the cell

diffusion of ATP out of the cell

toxic buildup of carbon dioxide inside the cell

inability to import sugar into the cell

toxic buildup of ethanol inside the cell

diffusion of ATP out of the cell

toxic buildup of carbon dioxide inside the cell

Explanation / Answer

Inability to import sugar into the cell is main aspect for the yeast cells demise
