Web26. mar 2024 · Selective permeability is mediated by special proteins that traverse the cellular membrane. They are involved in the movement of ions and small molecules as well as large polymers such as RNA and proteins. This movement can be passive or active – with or without the expenditure of energy. WebPermeability is the ability of a material to maintain a magnetic field (air has a permeability of 1) and is defined as the change in magnetic induction (B) for a given change in magnetic field (H). Mathematically, permeability is expressed as µ = ΔB / ΔH. As the magnetic field strength increases, so does the permeability — up to a point.

WebPermeability, the degree of openness of borders, is of crucial importance for people living in borderlands. The twentieth century saw each type of border regime: closed, semipermeable, and permeable. Some border regimes even ceased to exist, at least in one certain respect, for example, in economic terms. WebDrugs' permeability across biological membranes, epithelial cells, or endothelial cells is a critical factor that influences the absorption and distribution. Drugs may cross cell membranes through passive diffusion, facilitated passive diffusion, active transport, and pinocytosis. The drug's physicochemical properties (such as lipophilicity and ...
