Passive and active Transport 1

Front

What is Passive Transport?

Back

Passive Transport means no energy is used.

Front

What is Equilibrium in the context of cell transport?

Back

Equilibrium is when there is an equal amount of substance on either side of the membrane.

Front

Does Active Transport require energy?

Back

Yes, Active Transport requires energy to move molecules from low concentration to high concentration.

Front

What is the main characteristic of Passive Transport?

Back

The main characteristic of Passive Transport is that it does not require energy.

Front

What is Simple Diffusion?

Back

Simple Diffusion is the movement of molecules from an area of high concentration to an area of low concentration without the use of energy.

Front

What is Facilitated Diffusion?

Back

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

Front

What is Osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane.

Front

What is the difference between Active and Passive Transport?

Back

Active Transport requires energy to move substances against their concentration gradient, while Passive Transport does not require energy.

Front

What role do transport proteins play in cell transport?

Back

Transport proteins help facilitate the movement of substances across the cell membrane.

Front

What is a Concentration Gradient?

Back

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