What is passive transport?

Back

The movement of substances across a cell membrane without the use of energy, typically along the concentration gradient.

Front

What is active transport?

Back

The movement of substances across a cell membrane against the concentration gradient, requiring energy.

Define diffusion.

Back

The process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is facilitated diffusion?

Back

A type of passive transport that uses transport proteins to help move substances across the cell membrane.
