Flashcard - Cell Membrane

Front

What are the three types of transport that go from high to low concentration?

Back

Diffusion, Osmosis, Facilitated Diffusion

Front

What uses proteins (the proteins make a channel) to move molecules across the membrane without requiring energy?

Back

Facilitated Diffusion

Front

What are the two other names that you can use for the cell membrane?

Back

Plasma Membrane, Fluid Mosaic Model

Front

Which type of movement has proteins that act like pumps to move molecules through the cell membrane?

Back

Active Transport

Front

What type of solution is a cell in when it gets bigger than normal while in tap water?

Back

Hypotonic

Front

What is the primary function of the cell membrane?

Back

To protect the cell and control what enters and exits.

Front

What is osmosis?

Back

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

Front

What is diffusion?

Back

The movement of molecules from an area of high concentration to an area of low concentration.

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy.

Front

What is facilitated diffusion?

Back

A process where molecules pass through the cell membrane via protein channels without using energy.
