genetic from genetic from genetic from genetic from genetic from Alexus Caluin ame 1- One of the functions of cell membranes is to serve as permeability o 2- The initial identification o f lipids as major components of cell membranes was in part based on the fact that non pola substances could readily enter the cell. 3. Singer and Nicolson proposed the luidl mosaicmodel of cell membranes. 4. The Anphipore of phospholipids is ritical to heirolc in membranes 5- Phospholipids make up the fluid part of membranes, proteins make up the 6- 7- Membrane fluidity increases with decreasing levels of 8- Membrane fluidity nature of phospholipids is critical to their role in membranes. part. are required to catalyze the flip-flop of membrane lipids. -chain fatty acids. with increasing levels of unsaturated fatty acids. 9- Most of the specialized functions of a cell membrane depend on its proteins/lipids components (Underline what applies) 10-In animals cell membranes, cholesterol functions as a fluidity 11- The ability of some cells to regulate the fluidity of their membrane by altering its lipid composition is referred to as 2-In a membrane protein, the hydrophobic segments that span the lipid bilayer are called segments. membrane proteins are covalently attached to lipid molecules that are embedded within the bilayer. membrane proteins can only be solubilized by using detergents to disrupt (dissolve) the lipid bilayer. -The majority of carbohydrates in membranes are found as part of
