Without cholesterol, cell membranes would be too fluid, not firm enough, and too permeable to some molecules.]]> 2017-09-26 13:43:27 UTC https://padlet.com/Only_Ze/9l31afhpqmjw/wish/191242143 Only_Ze https://padlet.com/Only_Ze/9l31afhpqmjw/wish/191243065 roteins on the cell membrane surface often have short carbohydrate chains protruding out from the cell surface, known as glycolipids and glycoproteins. They form hydrogen bonds with the water molecules surrounding the cell and thus help to stabilize membrane structure.]]> 2017-09-26 13:45:03 UTC https://padlet.com/Only_Ze/9l31afhpqmjw/wish/191243065 Only_Ze https://padlet.com/Only_Ze/9l31afhpqmjw/wish/191244788  Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane]]> 2017-09-26 13:47:46 UTC https://padlet.com/Only_Ze/9l31afhpqmjw/wish/191244788 Only_Ze https://padlet.com/Only_Ze/9l31afhpqmjw/wish/191248185 they form the basic structure of a cell membrane, called the lipid bilayer. Scattered in the lipid bilayer are cholesterol molecules, which help to keep the membrane fluid consistent. Membrane proteins are important for transporting substances across the cell membrane.]]> 2017-09-26 13:52:26 UTC https://padlet.com/Only_Ze/9l31afhpqmjw/wish/191248185
