Lipids, mainly phospholipids, make up the bulk of the cell membrane. how is the structure of the phospholipid 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 to provide the energy to move molecules across the membrane d. the head of the phospholipid, which is hydrophilic, to control the movement of large hydrophobic molecules, and the tails of the phospholipid, which are hydrophobic, to control the movement of large hydrophilic molecules

Which statements accurately reflect the permeability of the cell membrane? choose all that apply. the hydrophilic part of the cell membrane is a, the phosphate head. the lipid tails are hydrophobic and will only allow molecules which are small and polar to pass through. molecules that are large or charged must use a channel protein, such as d, to cross the cell membrane. molecules using membrane proteins, such as e, for transport require energy, charged molecules, such as k* or ca** are unable to pass through the lipid bilayer because of their charge and must use a membrane protein to cross the cell membrane. c, the lipid tails, are hydrophobic and repel water.

the cell membrane is selectively permeable. o2 diffuses across the phospholipid bilayer. k+ must cross the cell membrane using a membrane protein. which property of the cell membrane prevents the diffusion of k+? a) the membrane proteins are attracted to the charged ions. b) only very small particles are able to diffuse across the cell membrane. c) the lipid tails are hydrophobic, repelling charged ions such as k+. d) the phosphate heads are hydrophobic and prevent the passage of polar substances.
