Cell Transport exam review

Front

What is Exocytosis?

Back

A type of active transport that uses a vesicle to expel large molecules from the cell.

Front

What is Facilitated Diffusion?

Back

A process of passive transport that allows substances to cross membranes with the assistance of special proteins.

Front

What happens to a cell in a fresh water solution?

Back

The cell expands and may burst (lyse) due to the influx of water.

Front

What is Diffusion?

Back

A type of passive transport where molecules spread from an area of high concentration to an area of low 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 a Concentration Gradient?

Back

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

Front

What role do cell membranes play in transport?

Back

Cell membranes regulate the movement of substances in and out of the cell.

Front

What is a Vesicle?

Back

A small membrane-bound sac that transports substances within a cell.
