12. Why do phospholipids place in water spontaneously form bilayers? (Multiple Choice) a) The "heads" of the phospholipids engage in hydrophobic interactions with the water molecules. b) The fatty acid "tails" engage in hydrogen bonding with the water molecules. c) Each of the molecules has a polar and non-polar region. d) The water molecules cannot interact with phospholipids since each has a different polarity. e) Lipid bilayers are required for the attachment of peripheral proteins.
Keemin L.
In a lipid bilayer, the ____ phospholipid tails point inward and form a region that excludes water. a. hydrophobic b. basic c. acidic d. none of the above e. hydrophilic
Qudsiya A.
Phospholipids assemble spontaneously into bilayers driven by the attraction of their "tail" portions to each other and of their "head" portions to each other. The "head" portions are: A. composed of carbon-hydrogen chains. B. nonpolar. C. hydrophilic. D. hydrophobic. E. directed away from intra- and extracellular fluid.
