Cell Transport

Front

What is the function of aquaporins?

Back

Facilitating transport of water.

Front

During active transport, molecules move...

Back

from low to high concentration.

Front

What cell structure is most responsible for maintaining homeostasis in cells?

Back

Cell membrane.

Front

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

Back

Simple diffusion.

Front

What type of diffusion uses protein channels to help molecules cross the cell membrane?

Back

Facilitated diffusion.

Front

Define passive transport.

Back

The movement of molecules 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 across a selectively permeable membrane.

Front

What is the role of the cell membrane?

Back

To protect the cell and regulate what enters and exits.

Front

What is the difference between active and passive transport?

Back

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

Front

What is facilitated diffusion?

Back

A process where molecules pass through the cell membrane via protein channels.
