Cell Transport Practice

Front

What happens to a cell when it is placed in a solution with a high salt concentration?

Back

The cell most likely shrinks due to water moving out of the cell to balance the salt concentration.

Front

What is the process called when water moves through a membrane?

Back

Osmosis.

Front

What is facilitated diffusion?

Back

A type of passive transport where channel proteins help larger molecules pass through the cell membrane.

Front

What regulates what can enter and leave the cell?

Back

The Cell Membrane.

Front

What type of transport does diffusion represent?

Back

Passive transport.

Front

What is the main function of the cell membrane?

Back

To control the movement of substances in and out of the cell.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What role do channel proteins play in cell transport?

Back

They form tunnels that allow specific molecules to pass through the cell membrane.

Front

What is the outcome of placing a cell in distilled water?

Back

The cell may swell and potentially burst due to water entering the cell.

Front

What is the term for the movement of molecules from an area of high concentration to an area of low concentration?

Back

Diffusion.
