Answer:
At high concentrations, alcohols reduce bilayer stability (12, 21) and break down the lipid bilayer barrier properties, causing increased ion permeability (14, 15).
Step-by-step explanation:
As the ethanol concentration increases, membrane permeability will increase. If the ethanol concentration is high enough, enough phospholipids will dissolve to cause the plasma membrane to disintegrate completely which will kill the cell.
