Question:

The ability of proteins to move laterally within the overall bilayer lipid molecules of plasma membrane is measured as its

Options:

1. Stability
2. Thickness
3. Degree of permeability
4. Fluidity

Solution:

The ability of proteins to move laterally within the overall bilayer lipid molecules of the plasma membrane is measured as its fluidity. Fluidity is an important property of the plasma membrane, as it affects the function of integral membrane proteins and the diffusion of molecules across the membrane. The fluidity of the membrane is influenced by several factors, including temperature, lipid composition, and the presence of cholesterol. High temperatures increase membrane fluidity, while low temperatures decrease it. The lipid composition of the membrane can also affect its fluidity, with shorter and more unsaturated fatty acid chains increasing fluidity. Cholesterol can also affect membrane fluidity, with low concentrations increasing fluidity and high concentrations decreasing it.
