Cell Membranes are contructed mainly of?
Cell membranes are made of a phospholipid bilayer.
Why Lipid bilayers form spontaneously?
The process is exergonic
What are the two most important characteristics of the lipid bilayers found in cell membranes?
Lipid bilayers are important because of their impermeability by water solutions and their regulation of ion intake into the cell.
Why do you think there are 2 lipid bilayers?
they need to control the amount going in and out
A lipid bilayer is characteristic of all membranes?
A lipid bilayer is characteristic of all biological membranes. Some membranes are double bilayers.

What are cell membranes constructed of?
Lipid Bilayers

What stuctural features of the plasma membrane contribute to its semipermeability?
lipid bilayers

A lipid bilayer is characteristic of all biological membranes. Some membranes are double bilayers.
What is another name for the phospholipid bilayer?
It depends on which lipid bilayer you're talking about. There is the phospholipid bilayer that surrounds eukaryotic cells, cholesterol phospholipid bilayers, protein lipid bilayers, phase transition lipid bilayer, lipid bilayer membrane...
Why is the skin permeable to organic solvents?
Because they can dissolve the lipid bilayers of epidermal and dermal cell plasma 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
Which function does the lipid bilayer component of the plasma membrane NOT provide for the cell?
The functions that the lipid bilayer component of the cell membrane does not provide for the cell are controls that exchange of mater and chemical information between one cell and adjacent cells or environment. The lipid bilayer provides an impermeable, self sealing membrane capable of dividing or fusing the cell without breaking.
