Answer» Answer: The nonpolar protein portions would separate the polar portions of the phospholipids from water, causing the bilayer to DISSOLVE. Meaning, the DAVSON-Danielli model is not only incorrect, but it is ALSO impossible. ... Because of this, the phospholipid bilayer sandwiched on the inside would remain isolated from the water.Sandwich or Lamellar models explained that cell membranes contain both proteins and LIPIDS in distinct layers. According to the Danielli and Davson model, plasma membrane consists of a double phospholipid layer and is surrounded on either side by a layer of hydrated globular proteins or P-L-L-P structure. |
