QUESTIONS LIST:

• extracellular fluid : this refers to a cell's watery surroundings.
• phospholipid bilayer : this describes the main structure of a cell membrane.
• fluid mosaic : this model of the cell membrane includes embedded proteins forming a mosaic pattern within the phospholipids, which can move laterally.
• selectively permeable : this property of a cell membrane allows it to control what goes in and out of the cell.
• glycolipids : these membrane lipids have an attached cho molecule and they give stability.
• cholesterol : these membrane lipids are embedded only in animal cell membranes.
• integral : this is the general name for proteins that are embedded wholly or partially within a cell membrane.
• peripheral : these proteins are attached to the inner or outer surface of the cell membrane.
• glycoproteins : these integral proteins, with cho chains attached, are cell-recognition proteins.
• channel : these integral proteins have channels through them, which allow molecules or ions through.
• carrier : these integral proteins have channels that are only open for certain ions or molecules, such as glucose.
