A double layer of phospholipids with proteins is the best statement that describes the structure of the cell membrane.
The cell membrane is made up of two layers of amphipathic lipids and also has 20% of integral and peripheral proteins.
In the two layers of amphipathic lipids, the hydrophilic polar heads (affinity for water) orient themselves in and out of the cell, keeping their hydrophobic (water-rejecting) parts in contact.
These lipids are primarily cholesterol, but also phosphoglycerides and sphingolipids.
The integral and peripheral proteins fulfill functions of connection, transport and catalysis, thanks to them there is also cell recognition, a form of biochemical communication.
Therefore, we can conclude that a double layer of phospholipids with proteins is the best statement that describes the structure of the cell membrane and that these fulfill a certain function.
