What is the membrane a phospholipid bilayer?

Answer 1

It is the double wall of a cell membrane that regulates material passage.

The cell membrane is called the phospholipid bilayer because the phospholipids form two distinct layers. In each layer, the phospholipid molecules lie with the hydrophilic "heads" at the membrane surface and the hydrophobic "tails" on the inside, in association with cholesterol and small quantities of other lipids.

Answer 2

An example of a phospholipid bilayer is the cell surface membrane of an animal or plant cell. It is made up lipids with a hydrophilic phosphate head and two hydrocarbon fatty acid tails. It also contains glycolipids and glycoproteins which act as receptors. There are also channel proteins for the transport of ions to the inside or outside of cells. There are the pumps which need energy to operate (by active transport).

Answer 3

The membrane is a phospholipid bilayer consisting of two layers of phospholipid molecules. This structure forms the foundation of cell membranes and helps regulate the passage of molecules in and out of the cell.

Answer 4

the twin layer of phospholipids forms most of the cell membrane and is used to prevent substances (water soluble of fat soluble, i forgot) from entering the cell by diffusion

Answer 5

The cell membrane
