Yes, it is possible.
Certain substances, such as small molecules and ions, are able to cross the cell membrane. The ability of a substance to cross the membrane is determined by its size, charge, and solubility in the lipid bilayer of the membrane.
Because the ions are charged, indicating high polarity, which lipids do not possess; they're hydrophobic, and therefore ions cannot pass through the lipid bilayer since lipids are highly unpolar, unless through an ion channel, which has a higher polarity
The lipid bilayer is impermeable to large polar molecules, such as ions and most proteins. It is also impermeable to water-soluble molecules that are not specifically transported across the membrane by proteins or channels.
Large polar molecules and ions generally cross lipid bilayers the slowest due to their size and charge, which hinders their ability to move through the hydrophobic interior of the membrane. Additionally, molecules that are not lipid soluble or do not have specific transporters in the membrane will also have difficulty crossing the lipid bilayer.
Bacteria prokaryotic cells and eukaryotic.
Large polar molecules and ions are the least likely to cross a membrane by simple diffusion due to their size and charge, which hinders their ability to pass through the hydrophobic lipid bilayer.
They can form a lipid bilayer. The lipid bilayer is the barrier that keeps ions, proteins and other molecules where they are needed and prevents them from diffusing into areas where they should not be.The phospholipids help the cell maintain its internal aqueous environment. (Apex)
Nope. It Is diffusion
it depends on what you are referring to. the lipid bilayer is exactly what it says.it is two layers compsed of lipids. lipid molecules have two properties: a hydophobi tail and a hydrophilic head. so when the bi layer is put together, it has the tails facing eachter and the heads out to react with water conditions in the body. the membrane is also embedded with proteins of all dffierent kinds that allows ions to cross and this allows for cell communication
The lipid bilayer that forms the cellular membrane forms an effective semi-permeable membrane. The lipid bilayer typically can typically exclude larger molecules based on size (molecular weight) and other molecules based on charge (ions and salts).
Fats can cross the cell membrane through passive diffusion, facilitated diffusion, or by being transported with the help of carrier proteins. These methods allow fats to move across the lipid bilayer and enter the cell for various cellular processes.
A channel-forming ionophore is a type of ionophore that can create a pore or channel in the lipid bilayer of a cell membrane, allowing specific ions to pass through. These ionophores facilitate the movement of ions across the membrane by forming a pathway for ion transport. Examples include gramicidin and amphotericin B.
