this means that it allows some materials, but not all, to cross it, or permeate it.
Yes, materials that enter the cell by phagocytosis also cross through the cell membrane, but in a different manner compared to passive or active transport. In phagocytosis, the cell membrane engulfs large particles or microorganisms, forming a vesicle that brings these materials into the cell. This process involves the membrane folding around the substance rather than allowing it to pass through like smaller molecules do in passive or active transport.
Materials cross the plasma membrane through processes such as simple diffusion, facilitated diffusion, and active transport. These processes involve the movement of substances across the lipid bilayer of the membrane with the help of transport proteins or by utilizing energy to move against a concentration gradient.
Proteins known as transporters or channels facilitate the movement of materials across the cell membrane. These proteins can be part of the cytoskeleton, which provides structural support and aids in the transport of vesicles and other cellular components. Additionally, motor proteins, such as kinesins and dyneins, interact with the cytoskeleton to move cargo within the cell, helping to transport materials to and from the membrane.
Materials that typically do not cross biological membranes include large polar molecules and ions, such as glucose and charged particles like sodium or potassium ions. These substances are often too big or have a charge that prevents them from passing through the lipid bilayer of the membrane. Instead, they require specific transport proteins or channels to facilitate their movement across the membrane. Additionally, certain large macromolecules, like proteins, are unable to cross the membrane without endocytosis or other specialized mechanisms.
A selectively permeable membrane allows SOME but not ALL materials to cross.
A membrane that lets all materials cross is permeable. A membrane that lets nothing cross is impermeable.
Some materials cross the cell membrane by diffusion. Some cross through channels. Some bind to receptors and are actively transported.
