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.

Which statement is true bout the plasma membrane? The proteins make up the matrix of the membrane_ The model can be likened to sandwich where phospholipids are like the bread and proteins are like the filling: The fluid nature of the membrane is regulated by flip-flopping of the phospholipids from one side of the membrane to the other: Proteins and phospholipids can move sideways within the plane of the membrane_
