Define active transport.

Back

Active transport is the movement of substances against their concentration gradient, requiring energy.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in concentration of a substance between two areas.

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a membrane via specific transmembrane integral proteins.
