Read the following statements regarding the plasma membrane and its functions. A. The quasi-fluid nature of lipid enables lateral movement of proteins within the overall bilayer. B. The fluid nature of the membrane is important for functions like cell growth, secretion, and endocytosis. C. Polar molecules can easily pass through the non-polar lipid bilayer by simple diffusion. D. The Na⁺/K⁺ pump transports ions acros

Step-by-step solution

Statement A is correct. According to the fluid mosaic model proposed by Singer and Nicolson, the quasi-fluid nature of lipid enables lateral movement of proteins within the overall bilayer. Statement B is correct. The fluid nature of the membrane is important for functions like cell growth, formation of intercellular junctions, secretion, endocytosis, and cell division. Statement C is incorrect. Polar molecules cannot pass through the non-polar lipid bilayer by simple diffusion. They require a carrier protein of th
