The selective permeability of a membrane refers to:

Select one:

a. The relative fluidity of the lipid bilayer under different conditions.

b. The movement of a molecule from an area of greater concentration to an area of lesser concentration.

c. The ability of only certain molecules to pass across a membrane.

d. The ability to recognize and/or attach to select extracellular components.

Answer 1

Ans) Option c is correct

REASON-The selective permeability of a membrane refers to the ability of only certain molecule to pass across a membrane by means of active or pasdive transport.

Rest all options are incorrect -

Option a is incorrect because the relative fluidity if lipid bilayer under certain conditions is termed as membrane fluidity.

Option b is incorrect because the movement of molecule from an area of greater concentration to an area of lesser concentration is termed as Diffusion or passive transport.

Option d is incorrect because the ability to recognize and /or attach to select extracellular components is function of plasma membrane.
