|
a protein bilayer with phospholipids embedded in the layers
|
|
a hydrophilic head and a hydrophobic tail
|
|
a phospholipid layer and a protein layer
|
Detailed explanation-1: -A plasma membrane consists of a lipid bilayer. This lipid bilayer is made up of an upper hydrophilic lipid layer, and a lower hydrophobic lipid layer. The plasma membrane contains transport protein . The proteins are embedded in the phospholipid bilayer.
Detailed explanation-2: -The phospholipid bilayer consists of two layers of phospholipids, with a hydrophobic, or water-hating, interior and a hydrophilic, or water-loving, exterior. The hydrophilic (polar) head group and hydrophobic tails (fatty acid chains) are depicted in the single phospholipid molecule.
Detailed explanation-3: -Four major phospholipids predominate in the plasma membrane of many mammalian cells: phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, and sphingomyelin.
