Cell Transport

Front

What is the process called when cells use energy to transport materials across the cell membrane?

Back

Active transport

Front

What happens to an animal cell when it is placed in a hypertonic (salty) solution?

Back

The cell will shrink.

Front

What type of passive transport involves the use of protein channels to help molecules cross the cell membrane?

Back

Facilitated diffusion.

Front

True or False: Active transport allows a cell to move molecules from an area of low concentration to an area of high concentration.

Back

True.

Front

Which of the following is NOT a type of passive transport: diffusion, osmosis, facilitated diffusion, or endocytosis?

Back

Endocytosis.

Front

What is diffusion in the context of cell transport?

Back

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

Front

What is osmosis?

Back

The diffusion of water molecules across a selectively permeable membrane.

Front

What is the main difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What role do transport proteins play in facilitated diffusion?

Back

Transport proteins help specific molecules cross the cell membrane without using energy.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to the inside of the cell, causing the cell to swell.
