What is the lipid bilayer impermeable to?
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.
What is the double layered sheet that makes up nearly all cell membranes called?
The double layered sheet that makes up nearly all cell membranes is called a lipid bilayer. This structure is composed of phospholipid molecules, with hydrophilic heads facing outward and hydrophobic tails facing inward to form a barrier around the cell.
How do Lipid-soluble molecules and gases enter the cell?
diffusion through the lipid bilayer.
What specific kind of lipid is used in membranes?
Phospholipids make up the lipid bilayer.
What moves through a lipid bilayer slowly?
Polar molecules and ions move through a lipid bilayer slowly due to their hydrophilic nature, which makes it difficult for them to pass through the hydrophobic core of the bilayer. Additionally, large molecules, such as glucose, also experience slow diffusion as they cannot easily penetrate the lipid environment. This slow movement often requires the assistance of transport proteins to facilitate their passage across the membrane.

What is another name for the phospholipid bilayer?
It depends on which lipid bilayer you're talking about. There is the phospholipid bilayer that surrounds eukaryotic cells, cholesterol phospholipid bilayers, protein lipid bilayers, phase transition lipid bilayer, lipid bilayer membrane...
What forms the boundary of the nucleus?
The nucleus has the same sort of boundary as the cell itself has. That is a lipid bilayer.
Can water cross the lipid bilayer?
Yes, water can cross the lipid bilayer through a process called simple diffusion.
What has the author H Ti Tien written?
H. Ti Tien has written: 'Planar bilayer lipid membranes (Progress in surface science)' 'Bilayer lipid membranes (BLM)' -- subject(s): Bilayer lipid membranes
Can nonpolar molecules cross the lipid bilayer?
Yes, nonpolar molecules can cross the lipid bilayer because the lipid bilayer is made up of nonpolar molecules itself, allowing nonpolar molecules to pass through easily.
Can CO2 diffuse through the lipid bilayer?
Yes, carbon dioxide (CO2) can diffuse through the lipid bilayer of a cell membrane.
Whattype of bilayer makes up most of the cell membrane?
lipid bilayer
What is lipid bilayer?
thin membrane made of two layers of lipid molecules.
How does lipid soluble move across the plasma membrane?
by dissolving in the lipid bilayer.
What kind of lipid is used in membranes?
Phospholipids make up the lipid bilayer.
