WebMay 18, 2016 · Small non-polar molecules such as oxygen and carbon dioxide have no charge and can pass directly through the membrane. Polar substances, with the exception of water, present problems for the membrane. While some polar molecules connect easily with the outside of a cell, they cannot readily pass through the hydrophobic core of the … WebThe membrane. The membrane is made from a polymer which only allows positive ions to pass through it. That means that the only the sodium ions from the sodium chloride solution can pass through the membrane - and not the chloride ions.
