Question

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

Unfortunately, the grape juice is contaminated with proteases that attack some of the transport proteins in the yeast cell membrane, after a while the yeast cell dies. Which of the following could account for the yeast cell's demise?
a) Toxic build up of carbon dioxide
b) Toxic buildup of Water
c) diffusion of ATP out of the cell
d) Inability to import sugar into the cell

Answer 1

The demise of the yeast cell in the grape juice can be accounted for by the inability to import sugar into the cell.

Step-by-step explanation:

The demise of the yeast cell in the grape juice can be accounted for by the inability to import sugar into the cell. The contaminated grape juice attacks some of the transport proteins in the yeast cell membrane, making it unable to transport sugar into the cell to be used for energy production. As a result, the yeast cell is unable to survive and eventually dies.
