Passive Transport

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 process where molecules move from a high concentration to a low concentration.

Front

What is Selective Permeability?

Back

The ability of the cell membrane to allow some substances to pass through while preventing others.

Front

What is Equilibrium in the context of cell transport?

Back

A state where there is an equal amount of substance on either side of the cell membrane.

Front

What regulates what enters and leaves a cell?

Back

Cell Membrane.

Front

What is Osmosis?

Back

The diffusion of water molecules across a selectively permeable membrane.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will lose water and shrink.

Front

What happens to a cell in a hypotonic solution?

Back

The cell will gain water and may swell or burst.

Front

What is facilitated diffusion?

Back

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

Front

What is the role of transport proteins in passive transport?

Back

They help move substances across the cell membrane without using energy.
