extracellular signaling is one example
Some molecules are too large to pass through the cell membrane without transport proteins.
Receptor proteins.
Through proteins in the membrane.
Actually, bilipid "heads" form the layers of the membrane, but there are carrier proteins that transport objects into and out of the cells. These carrier proteins use either active or passive transport to get objects across the membrane. Active transport uses energy, while passive transport doesn't need to use energy to get items across. Hope this helps!!!
The plasma membrane separates the interior of cells from the outside environment. The function of this membrane is to protect the cell from its surroundings. The membrane proteins provide many functions that is vital for survival of the organism. These proteins may act as a membrane receptor and relay signals between the cells internal and external environments. Also transporting proteins by moving molecules and ions across the membrane.

Channel proteins, a type of transport proteins to the cells, move molecules from outside of the membrane to the inside

They do not differ much. The proteins in each are slightly different.
