Answer:

Explanation:

Protein deeply embedded in the bilayer are called integral membrane proteins. Most of this integral membrane proteins span the whole bilayer and they are called Transmembrane protein.

Because many molecules and ions can not pass through the hydrophobic core of the cell membrane they need a carrier mediated transport to go in and out of the cell. Transmembrane protein serves as channels, receptors (hormones, growth factors, neurotransmitter), tissue specific antigens, ion channels, membrane based enzymes etc that moves in and out of the cell.

The proteins embedded in the cell membrane helps cells to communicate with one another and maintain their shapes. It also helps them carry out changes triggered by chemical messengers, and transport and in the distribution materials.

Cell membrane

The cell membrane is the membrane which is found in all cells. It separates the internal part of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane is also known as the plasma membrane as it also helps regulates the transport of materials entering and exiting the cell.
