- 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.arrow_forwardWhich of the following functions is NOT made possible by lysosomes? Group of answer choices breakdown of large molecules synthesize in lipids digest waste products protect the cell from foreign invadersarrow_forwardWhich of the following statements best describes the movement of molecules in a cell if its concentration on both sides is the same? Group of answer choices The molecules will stop moving across the membrane. The molecules will continue to move across the membrane in both directions. The molecules will move across the membrane to the outside of the cell. The molecules will move across the membrane to the inside of the cell.arrow_forward
