WebDec 28, 2024 · Why can’t ions pass through the membrane? Even the smallest of ions — hydrogen ions — are unable to permeate through the fatty acids that make up the membrane. If ions “want” to enter the cell due to a high concentration of that type of ion on one side of the cell, they can do so by entering through the protein channels that are ...
