Back

Endocytosis

Front

What type of passive transport involves the use of carrier proteins?

Back

Facilitated Diffusion

Front

What is a selectively permeable membrane?

Back

A membrane that allows some substances to pass while blocking others.

Front

Does active transport move molecules from low concentration to high concentration?

Back

True

Front

What is the term for the energy-requiring process of moving materials across a cell membrane?

Back

Active transport

Front

What is passive diffusion?

Back

The movement of molecules from an area of high concentration to an area of low concentration without energy.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What role do carrier proteins play in facilitated diffusion?

Back

They help transport specific substances across the cell membrane.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy; passive transport does not.

Front

What is the Na/K pump?

Back

A type of active transport that moves sodium out of and potassium into the cell.
