What else can I help you with?
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.
How do water-soluble molecules diffuse through the cell membrane?
Water-soluble molecules diffuse through the cell membrane by passing through protein channels or transporters that are embedded in the membrane. These channels and transporters allow the molecules to move across the membrane, from an area of high concentration to an area of low concentration, without requiring energy.
Do lipid soluble molecules diffuse into a cell more rapidly than water soluble molecules?
Yes, lipid soluble molecules diffuse into a cell more rapidly than water soluble molecules. This is because the cell membrane is primarily made up of lipids, so lipid soluble molecules can easily pass through the lipid bilayer, while water soluble molecules need specific channels or transporters to facilitate their entry into the cell.
The interior of the lipid bilayer of a cell membrane forms a nonpolar zone that?
The nonpolar zone in the lipid bilayer of a cell membrane helps to repel polar molecules, allowing for selective permeability of the membrane. This structure is essential for maintaining cell integrity and regulating the passage of substances in and out of the cell.
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.
The reason that water soluble molecules cannot enter certain regions of the plasma membrane is due to the presence of?
hydrophobic tails of phospholipids in the plasma membrane, which create a barrier that repels water-soluble molecules. This limits the passive permeability of water-soluble molecules through the membrane.

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.
The soluble portion of cytoplasm including molecules and small particles such as ribosomes but not organelles covered with membranes?
cytosol

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.

Which part of membrane is hydrophobic?
The lipid bilayer of the cell membrane is hydrophobic, composed of fatty acid tails that repel water molecules. This hydrophobic core provides a barrier that prevents water-soluble molecules from freely passing through the membrane.
