Cell Transport

Front

What happens to a cell in a hypertonic solution?

Back

The cell will shrink.

Front

What is the movement of molecules from high to low concentration using protein channels called?

Back

Facilitated transport.

Front

What is the process of moving materials from high to low concentration through a protein channel?

Back

Passive Transport.

Front

What is the movement of molecules from low to high concentration using protein pumps called?

Back

Active transport.

Front

What is the movement of water from high to low concentration called?

Back

Osmosis.

Front

Define osmosis.

Back

The movement of water molecules from an area of high water concentration to an area of low water concentration through a semi-permeable membrane.

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 active transport?

Back

The movement of substances against their concentration gradient, from low to high concentration, requiring energy.

Front

What role do protein channels play in facilitated transport?

Back

They provide a pathway for specific molecules to cross the cell membrane without using energy.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion is the movement of solute particles from high to low concentration, while osmosis specifically refers to the movement of water.
