Cell Transport

Front

What part of a phospholipid is hydrophilic?

Back

Phosphate group.

Front

What is the process called when molecules move from high to low concentration without the input of energy?

Back

Diffusion.

Front

In active transport, does the cell need to provide energy?

Back

Yes.

Front

Which of the following is NOT an example of passive transport?

Back

Membrane pumps.

Front

Which type of solution has fewer solutes in it than the cell does?

Back

Hypotonic.

Front

What is the definition of 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 facilitated diffusion?

Back

A process where molecules pass through the cell membrane with the help of special proteins, moving from high to low concentration without energy.

Front

What is the role of membrane proteins in cell transport?

Back

They assist in the transport of substances across the cell membrane.

Front

What does hypertonic mean in relation to cell solutions?

Back

A solution that has a higher concentration of solutes compared to the inside of the cell.

Front

What is the main difference between passive and active transport?

Back

Passive transport does not require energy, while active transport does.
