WebThe cell membrane structure is comprised of phospholipids, membrane proteins, glycolipids, glycoproteins and cholesterol. This is described as the 'fluid mosaic model'. Solvents and temperature affect the cell membrane structure and permeability. To investigate how temperature affects cell membrane permeability, beetroot cells can be used. WebThe amount of cholesterol in animal plasma membranes regulates the fluidity of the membrane and changes based on the temperature of the cell’s environment. In other words, cholesterol acts as antifreeze in the cell membrane and is more abundant in animals that live in cold climates.
