WebAug 23, 2014 · The cell membrane is mainly composed of phospholipids, which can easily be dissolved by alcohol. This results to an increase in the permeability of the cell membrane. WebFirstly, ethanol is permeable to cell membranes (Kinseth, 2006). Because of the nature of ethanol as a chemical is it able to get into the cell very easily through passive transport (Koszler, 2013). This disrupts the balance of the cells' aqueous environment (Morrow, 2009). WebTo be absorbed, alcohol moves across the epithelial cells, through the interstitial space, and into the capillaries. The capillaries are made of endothelial cells. As alcohol moves through each of these cells, it moves in the direction of the concentration gradient.
