Passive Transport Flashcard Review

Front

What is Facilitated Diffusion?

Back

The movement of specific molecules across cell membranes through protein channels with the concentration gradient.

Front

What is Simple Diffusion?

Back

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

Front

What happens to a cell when water moves into it?

Back

The cell swells due to the influx of water.

Front

What is a Concentration Gradient?

Back

A difference in the concentration of a substance across a distance.

Front

In which direction does water move during osmosis?

Back

From low to high solute concentration.

Front

What is Passive Transport?

Back

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

Front

What is Active Transport?

Back

The movement of substances against their concentration gradient, requiring energy.

Front

What is Osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is Equilibrium in terms of concentration?

Back

A state where the concentration of a substance is equal throughout a space.

Front

What role do protein channels play in facilitated diffusion?

Back

They provide a pathway for specific molecules to cross the cell membrane.
