SUMMARY
Ethanol easily crosses cell membranes due to its small size and unique molecular structure, despite being hydrophilic. It disrupts cellular functions by interacting with the lipid bilayer, which allows small, polar molecules to diffuse freely. Ethanol's two-carbon alkyl group reduces its polarity compared to water, facilitating its passage through phospholipid membranes. This discussion clarifies that ethanol does not require transport proteins to enter cells, as its molecular characteristics enable passive diffusion.
