Questions and Answers

What hypothesis did Gorter and Grendel present regarding the cell membrane?

  • The cell membrane is a rigid structure.
  • The cell membrane is primarily composed of a lipid bilayer. (correct)
  • The cell membrane contains proteins and lipids.
  • Membrane proteins are embedded within the lipid layer.
  • The Sandwich Model proposed that the membrane is made of two layers of lipid separated by proteins.

    False

    What did the Fluid Mosaic Model conclude about the movement within the membrane?

    Membranes are fluid and allow movement of membrane components.
