Cell and Cell Transport

Front

What is facilitated diffusion?

Back

Transport that uses proteins to help move molecules across the membrane.

Front

Which of the following is the best example of osmosis?

Back

Water moving through the cell membrane.

Front

What is it called when molecules move across the cell membrane from an area of high concentration to an area of low concentration through a carrier protein?

Back

Facilitated Diffusion.

Front

What structure of the cell forms a frame that holds the cell up in the cytoplasm?

Back

Cytoskeleton.

Front

Which of the following is correct about the Golgi?

Back

Modifies and packages molecules.

Front

What is the primary function of the cell membrane?

Back

To protect the cell and regulate what enters and exits.

Front

Define osmosis in the context of cell transport.

Back

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

Front

What is active transport?

Back

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

Front

What role do proteins play in facilitated diffusion?

Back

They act as channels or carriers to help transport molecules across the cell membrane.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion refers to the movement of any molecules from high to low concentration, while osmosis specifically refers to the movement of water.
