Front

What is the definition of Selective Permeability?

Back

The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

Front

What is Passive Transport?

Back

The movement of substances across a cell membrane without the use of energy.

Front

What is Diffusion?

Back

The movement of molecules from an area of high concentration to an area of low concentration.

Front

What is Facilitated Diffusion?

Back

The process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What role does the cell membrane play in passive transport?

Back

It acts as a barrier that selectively allows certain substances to pass through.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy, while passive transport does not.
