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.

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 is the name of the cell proteins and a lipid bilayer barrier?
Cell proteins are often referred to as integral membrane proteins or peripheral membrane proteins, depending on their association with the lipid bilayer. The lipid bilayer barrier is primarily composed of phospholipids, which have a hydrophilic head and hydrophobic tail that create a semi-permeable barrier for the cell.
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.
What particles can diffuse directly through the lipid bi-layer?
As the bilayer contains hydrophobic fatty acid tails, water-soluble molecules cannot diffuse directly through. However, lipid soluble molecules such as oxygen can diffuse directly through. Overall, for a molecule to be able to diffuse directly through it must be lipid-soluble, relatively small and non-polar.

Can the lipid pass through the cell membrane?
yes. Lipid soluble substances are highly permeable
How does lipid solubility affect the ability of substances entering a cell?
Lipid-soluble substances can easily pass through the cell membrane due to the presence of phospholipids that make up the membrane. These substances can dissolve in the lipid bilayer and diffuse through it, allowing them to enter the cell more readily. In contrast, substances that are not lipid-soluble may require specific transport mechanisms to facilitate their entry into the cell.
How does lipid soluble move across the plasma membrane?
by dissolving in the lipid bilayer.
What characteristic of cell membranes may explain why fat-soluble substances such as chloroform and other rapidly affect cells?
The lipid bilayer structure of cell membranes allows fat-soluble substances like chloroform to easily pass through them. This is because these substances can dissolve in the hydrophobic interior of the lipid bilayer, making it easier for them to enter the cells quickly and affect them rapidly.
What characteristics of cell membranes may explain why fat soluble substances such as chloroform and ether rapidly affect cells?
Cell membranes are composed of a lipid bilayer, which is impermeable to water-soluble substances but allows fat-soluble substances to easily pass through. Fat-soluble substances like chloroform and ether can dissolve in the lipid bilayer of the cell membrane and penetrate cells rapidly, leading to their rapid effects on cells.
How do Lipid-soluble molecules and gases enter the cell?
diffusion through the lipid 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.
What substances easily diffuse a class of cell membrane?
Lipid-soluble substances, such as oxygen, carbon dioxide, and small non-polar molecules, easily diffuse across the cell membrane. These substances can pass through the lipid bilayer of the membrane without the need for specific transport proteins.
Which substances is a nonpolar molecule that is not soluble in water?
Lipid
Why will water-soluble molecules have a hard time moving through the lipid bilayer of a cell?
false
