Lipids, mainly phospholipids, make up the bulk of the cell membrane. Which of these best compares how the structure of the phospholipid is so perfectly paired to the function of the cell membrane? A) Phospholipids are bulky/large molecules that prevent all molecules from entering/exiting the cell.
B) The polar tails of the phospholipids provide the barrier between the exterior/interior hydrophilic environments.
C) Lipids contain high energy bonds, and these bonds help to provide the energy to move molecules across the membrane.
D) The head of the phospholipid, which is hydrophilic, helps to control the movement of large hydrophobic molecules, and the tails of the phospholipid, which are hydrophobic, help to control the movement of large hydrophilic molecules.
