What can you conclude about the cell membrane structure if liquid soluble molecules move across the membrane?

It can be concluded that if the liquid soluble molecules move more readily across the membrane then the membrane must be made of lipids. When two parts are made of similar material then they will be more likely to allow other particles like them to pass.

What molecules that are soluble can pass through the fatty acid portion of the cell membrane unassisted?
Cholestrol
How do hydrophobic and hydrophilic relate to the structure of a cell membrane?
The cell plasma membrane is made of bipolar fatty acids with the fatty (uncharged) hydrophopic part pointed towards the inside of the plasma membrane and the hydrophillic (charged) part facing the inside of the cell or the outside of the cell.
Molecules can pass through the cell membrane of the human cell?
The molecules that can pass through the cell membrane of the human cell include water. Other molecules include fat soluble vitamins.
The interior of the lipid bilayer of a cell membrane forms a nonpolar zone that?
A nonpolar zone is formed in the interior portion of a cell membrane. This zone has the ability to prevent large molecules and ions from entering through the membrane.
Why can molecules that are fat-soluble permeate across a cell membrane?
Cell membranes are composed of a lipid bilayer. Cellular fluid (cytosol) and the cell's organelles are contained by the cell's membrane, which is composed of a lipid bilayer. Lipids are a type of fat. Because a cell's membrane is composed of fat, only fat-soluble molecules are able to dissolve through the membrane into the cytosol.
What molecules that are soluble can pass through the fatty acid portion of the cell membrane unassisted?
Cholestrol
Why can only molecules that are fat soluable permate a cell membrane?
The cell wall itself is made of lipid. To be more precise, the cell membrane is made of a bilayer of phospholipids. The hydrophobic fatty acid tails prevent water-soluble molecules passing through, but allow the transport of lipid-soluble molecules.

What substance is most likely to passively diffuse across the plasma membrane by dissolving in the membrane?
Lipid-soluble molecules such as O2 and CO2 diffuse freely through the plasma membrane.
What type of molecules can permeate the plasma membrane?
Any molecule smaller than the holes in the membrane can pass through is the membrane is permeable. If the membrane is semi-permeable, then only molecules that the membrane selects can pass through. Electronegativity and existence of lipid layers are common selective traits for semi-permeable membranes.
The permeability of a cell membrane depends on the ability of a molecule to diffuse across that membrane. Usually only molecules that are fat-soluble can permeate a cell membrane because?
Most of the bilayer is hydrophobic; therefore water or water-soluble molecules do not pass through easily. Usually only fat soluble are allowed through.A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer Some membrane proteins have carbohydrates attached to them, forming glycoproteins that act as identification markers.

Why are fat soluble molecules the only molecules that permeate across a cell membrane?
Because small non polar molecules are the ones able to cross due to the fact that the membrane consists of a phospholipid bilayer where the middle is composed on non polar tails
What role do carrier protein play in facilitated diffusion?
it moves large molecules or molecules that are not soluble in lipids across across the cell membrane. (Pg. 101 in science book...1st para.)

A nonpolar zone is formed in the interior portion of a cell membrane. This zone has the ability to prevent large molecules and ions from entering through the membrane.
