Question

Can someone please explain how cell membranes work. I am trying to do a assignment all about cell membranes and I dont really understand it that much.​

Answer 1

The cell membrane is made of a “phospholipid bi-layer”, what that means is it has two layers of these special lipids. they have “heads” and “tails”. the head (circle structure) is adaptable and likes watery enviroments (hydrophilic). the head faces in cytoplasm of the cell, and the outside enviroment as well. the tails of the phospholipid are hydrophobic (afraid of water). they are made of fatty acids. along this membrane, there are several proteins and other molecules. some of these protists serve as “passageways” into the cell. molecules and chemicals can travel through the protein channel into the cell to be used. often there are also other molecules on the outside of the cell membrane to help receive and relay chemical messages, these come in the form of carbohydrate chain
