Can CO2 pass through the phospholipid bilayer?
oxygen
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
Which materials will pass through the bilayer?
oxygen and carbon dioxide.
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 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.
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.

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
Water freely moves through a phospholipid bilayer Why is this unexpected?
It moves through the bilayer via channels. These channels often are for transfer through the bilayer for other chemicals (sodium, potassium, etc) but also allow water to flow through readily. It is unexpected because water is hydrophilic (obviously- all charged molecules are). The phosphate part of the bilayer can bind with water, but the lipid on the inside of the bilayer acts like a layer of oil on the surface of the water- water cannot pass through the hydrophobic lipid.
What are molecules on the cell membrane responsible for?
Letting different molecules in and out of a cell. Chemicals including steroid hormones, reactants and products of respiration...ect. the chemicals have to pass through the phospholipid bilayer (which is made from phosphates and fatty acid chains) molecules pass through the bilayer through passive diffusion, facilitated diffusion and active transport.
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.
