The ________ of a Cell Membrane Indicates How Easy It

Question

The ________ of a cell membrane indicates how easy it is for substances to cross.
A) thickness
B) pliability
C) density
D) permeability
E) charge

Accepted Answer

Permeability is the property of a membrane that determines how easily substances can cross, either by passive diffusion or facilitated transport. The higher the permeability, the easier it is for substances to cross the membrane. Thickness, pliability, density, and charge can affect permeability but do not define it.
