Cell Membranes in a Fluid Mosaic Model :)

Lately in Biology we have been learning about the cell membrane and what exactly is in the cell membrane!  The cell membrane is a phospholipid bilayer.  The phospholipid bilayer has hydrophobic tails, which means they are attracted to water.  The phospholipid bilayer also has hydrophilic heads, making them scared of water.  Inside the phospholipid bilayer there are glycoprotein, proteins, cholesterol, glycolipids, carbohydrates, and many others.  In the cell membrane there is a protein channel.  After reading the word protein channel, using common knowledge, I just thought it was a type of system that carried along proteins throughout the membrane.  Well, in scientific terms, the protein channel are cells that create and install their own protein channels which are also called membrane structure, because cells need a way to move useful substances into themselves and pump the waste outside.  The proteins act like little machines moving around other molecules.  I also learned that carbohydrate chains serve as recognition makers.  We created cell membrane posters and labeled everything that was in a cell membrane.
