What is the lipid bilayer impermeable to?
The lipid bilayer is impermeable to large molecules and small polar molecules. Only water and gas can easily pass through the bilayer.
What substance can pass through the lipid bilayer i.e. in between the phospholipid molecules?
Lipid solublewater insolublenon-polarnon-ionized
What can pass through the bilayer with ease?
Molecules that are not polar or ion molecules. That is because they won't be stopped by the hydrophobic tails and they will have the acknowledgement to pass through the cell membrane thanks to little resistance. This makes those molecules have an advantage.
What are 3 molecules that pass through the lipid bilayer of the cell membrane?
oxygen, carbon dioxide, and water
How does a plasma membrane determine selectivity of molecules?
Plasma membrane possesses specific protein channels and lipid bilayer. Protein channels are of million different types, each allow a specific molecule to pass through it regarding its size, shape, charges on it, solubility, etc. Fat soluble molecules pass through lipid bilayer.
What molcule can pass through a lipid bilayer by simple diffusion with no assistance from proteins?
Carbon.water molecules,glucose molecules can pass through lipid bilayer by simple diffusion

Some steroid hormones do not require a membrane receptor because?
they are lipid soluble and pass through the bilayer
What are 3 molecules that pass through the lipid bilayer of the cell membrane?
oxygen, carbon dioxide, and water
Are non polar molecules able to cross lipid bilayer?
Yes, Since the lipid bilayer of cells is nonpolar, only non-polar substances can pass directly through the bilayer without the need for any help by membrane transport proteins.
Is the lipid bilayer permeable to most water-soluble substances?
The lipid bilayer is impermeable to most water-soluble substances.The bilayer, most of which is a phospholipid bilayer, is permeable only to small, non-polar substances.In nature, the most common compounds to pass through the bilayer are carbon dioxide and oxygen.Scientists differ over how much water passes in and out of cells through the bilayer; some passes through special transport proteins called aquaporins.

Is glucose permeable through phospholipid bilayer?
Glucose does not readily diffuse across a lipid bilayer. In order for glucose to travel into the cell, it needs the help of a transport protein. This is called a facilitated diffusion.
How does lipid solubility affect the ability of substances entering a cell?
If the substance is not lipid soluble, it will not be able to pass through the cell membrane, which is a phospholipid bilayer. This means it will not be able to enter the cell.
