Cell Transport Review

Front

What is Exocytosis?

Back

A form of active transport where materials are expelled from the cell through vesicles that fuse with the cell membrane.

Front

What is Active Transport?

Back

The movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is the Cell Membrane?

Back

A protective barrier that surrounds the cell, regulating what enters and leaves.

Front

How do cells maintain homeostasis?

Back

By regulating what enters and leaves the cell, ensuring a stable internal environment.

Front

What is Facilitated Diffusion?

Back

The process of passive transport of molecules across a cell membrane via a specific carrier protein.

Front

What is Passive Transport?

Back

The movement of substances across a cell membrane without the use of energy, typically from high to low concentration.

Front

What is Osmosis?

Back

The diffusion of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is Pinocytosis?

Back

A type of endocytosis where the cell engulfs liquid from the surrounding environment.

Front

What is Endocytosis?

Back

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

Front

What is the role of Carrier Proteins?

Back

Proteins that assist in the transport of substances across a cell membrane, especially during facilitated diffusion.
