Which statement correctly explains the fluidity of the plasma membrane in the fluid mosaic model?
In the fluid mosaic model, the quasi-fluid nature of the lipid bilayer allows proteins to move laterally within it. This movement is measured as membrane fluidity and is important in processes such as secretion, endocytosis and cell division.
