Which of the following statements about the lipid bilayer portion of the plasma membrane is false? The lipid bilayer forms a permeability barrier to polar and charged substances The lipid bilayer confers fluidity to the plasma membrane The sole function of the phospholipids is to provide an inert matrix in which functionally important membrane proteins can be embedded The lipid bilayer defines the boundaries of the cell

This is because the phospholipids that make up the bilayer have a hydrophilic head and a hydrophobic tail. The hydrophilic heads face the outside of the cell and the inside of the cell, while the hydrophobic tails face each other in the middle of the bilayer. This Show more…

Which one of the following statements is false? a) Cellular membranes are made of a bilayer of phospholipids with each layer's fatty acids directed toward each other. The fatty acids are hydrophobic. b) The phosphate group of a lipid is hydrophobic and repelled by water. c) Organelles that are part of the endomembrane system are extensions of the plasma (cell) membrane. d) Various proteins are embedded within the plasma membrane. These proteins might act as "carrier" proteins, as structural proteins or as recognition proteins. e) Cholesterol is critically important to the strength of plasma membranes.

Which statement or statements about the plasma membrane are false? (more than one answer may apply) Plasma membranes contain proteins, lipids, polypeptides and nucleic acids. Cholesterol contributes to the fluid nature of the membrane. It gives the membrane some flexibility. It has a hydrophobic exterior (facing water) and a hydrophilic interior (facing other phospholipids) Plasma membrane of plant cells contain cellulose to provide structure, support and protection to the cell. Protein channels are embedded in the membrane.

Which of the following statements about a typical plasma membrane is correct? The hydrophilic interior of the membrane is composed primarily of the fatty acid tails of the phospholipids. Carbohydrates on the membrane surface are important in determing the overall bilayer structure. Phospholipids are the primary component that determines which solute can cross the plasma membrane. The two sides of the plasma membrane have different lipid and protein composition. The plasma membrane is covalently linked network of phospholipids and proteins that controls the movement of solutes into and out of a cell.
