Front

Phagocytosis

Back

A type of endocytosis in which a cell engulfs large particles or whole cells.

Front

Exocytosis

Back

Process by which a cell releases large amounts of material.

Front

Facilitated Diffusion

Back

Movement of large molecules such as sugar across cell membranes through protein channels.

Front

Endocytosis

Back

The process by which cells take in substances by engulfing them.

Front

Osmosis

Back

The diffusion of water across a selectively permeable membrane.

Front

Aquaporins

Back

Protein channels in the cell membrane that facilitate the passage of water.

Front

True or False: Exocytosis are the channels in the cell membrane that allow passage of water.

Back

False.

Front

True or False: Protein pumps use energy from ATP to pump small molecules and ions across the cell membrane.

Back

True.

Front

Diffusion

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

Active Transport

Back

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