Plasma Membrane Structure and Function
The Glycoproteins and glycolipids have a similar function. They both have lipids (otherwise known as fats) or proteins that carry carbohydrate chains. Speaking of which, carbohydrate chains make cell to cell recognition possible like fingerprints for cells to know they are in contact with one another. It acts like receptors for chemical messengers also.
There are six types of proteins that help with cellular transportation. These are channel, carrier, cell recognition, receptor, enzymatic, and junction.
Channel proteins have channels in them that molecules pass through to go in or out of a cell, much like the hallways in a school.
Carrier proteins are more specific, considering they combine with a molecule to help the particles get across the membrane, much like a door.
Enzymatic proteins carry out metabolic reactions for your cells, such as breaking down your food, so it is easily digested. This could be compared to a knife, which breaks down your food so it can be digested easier.
The last protein is the receptor protein, which has a binding site for a specific molecule, much like a lock that requires a specific key.
