Respuesta :

Lipids and proteins are the macromolecules that make up the majority of the cell membrane’s structure.

The cell membrane can be described as a semi-permeable membrane that allows selective entry of materials into and out of a cell.

The cell membrane is made up of a phospholipid bilayer. This phospholipid bilayer is amphipathic in nature i.e having hydrophobic tails and hydrophilic heads. The heads are pointed outwards, whereas the tails are embedded in between.

Besides phospholipids, cholesterol is also present in the structure of the cell membrane.

The cell membrane also has proteins embedded in it. These proteins act as carrier molecules and facilitate the entry of various hormones, ions, etc inside the cell membrane. The cell membrane consists of intrinsic as well as extrinsic proteins.
