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.
What increases the strength of the hydrophobic interactions in lipid bilayers and thus makes them less permeable to polar molecules?
increasing the length of hydrocarbon tails
The lipid bilayer is made up of a triple layer of phospholipids?
Cell membrane is made up of lipid bi layer. It is selectively permeable to some substances only. It plays very important role in integrity of the cell.
How is the cell membrane involved in regulating osmosis?
It is semi-permeable to water, in which water can pass it through the double lipid layer or through proteins crossing the double layer of the cell membrane.
Is the cell membrane permeable to ethanol?
Ethanol is a type of alcohol and alcohol breaks apart the weak hydrogen bonds in the lipid bilayers of cell membranes, which in turn, means it's denaturing. Once a membrane denatures, it no longer has a function so it becomes more permeable and it's less selective.
Can the lipid pass through the cell membrane?
yes. Lipid soluble substances are highly permeable
How semi-permeable is a cat's skin?
A cat's skin is mostly non-permeable - it is very water repellant. However, some lipid-soluble chemicals can be absorbed through the skin.
Why is the skin permeable to organic solvents?
Because they can dissolve the lipid bilayers of epidermal and dermal cell plasma membranes.

Why does drinking iced tea curb your appetite?
Because it's full of methanogens and they react with your gastrointestinal acids, forming a permeable lipid that is injected into your stomach.
What feature of a cell prevent water from entering the cell?
Nonpolar lipid layers
What are two main components of cellular membranes?
Partially permeable , permeable , immpermeable .
What is the phone number of the Bolsters Mills Village Library in Harrison?
The phone number of the Bolsters Mills Village Library is: 207-583-6421.
Osmosis occurs as water can cross the lipid bilayer through what?
The cell membrane is permeable to water molecules even though they are polar, due to the fact that water molecules are small.
