semipermeabilitetevnen
Semipermeabilitetevnen, often translated as semipermeability or selective permeability, refers to the property of a biological membrane to allow certain molecules or ions to pass through it by diffusion, and occasionally specialized facilitated diffusion, while blocking or slowing the passage of others. This selective nature is crucial for cellular function, as it enables cells to maintain internal environments distinct from their surroundings, control the influx and efflux of nutrients and waste products, and establish electrochemical gradients.
The permeability of a membrane is determined by the physical and chemical properties of both the membrane
This selective passage is essential for a wide range of biological processes, including nutrient uptake, waste
