Fluid mosaic model of plasma membrane shows that

Options

  1. Aquasi-fluid nature of lipid enables lateral movement of proteins within the overall bilayer.
  2. Bthe lateral movement within the membrane is measured as its fluidity.
  3. Cthe fluid nature of membrane is important for growth, formation of intercellular junctions, secretion, endocyt
  4. DAll of the above

Correct answer

D. All of the above

Step-by-step solution

Singer and Nicolson states that cell membrane is considered to be highly fluid. The integral proteins are capable of showing lateral diffusion in the lipid bilayer, studies with NMR (Nuclear Magnetic Resonance) and ESR (Electron Spin Resonance) technique indicate that lipid bilayer has many dynamic motional properties. Quasifluid nature of lipid enable lateral movement of proteins within the overall bilayer The fluid nature of membrane is important for growth, formation of intercellular junctions, secretion endocyt
