Well give you challenging practice questions to help you achieve mastery of ap biology. When you have a membrane that allows the passage of some things but not others, that membrane is said to have this is true of all cell membranes, which tend to allow the passage of lipids, gasses, but do not allow proteins or ions or large polar molecules. This does not mean that there is no movement through the membrane, however, just that the movement is such that the concentrations stay the same.
