Front

What must a particle use to move through the cell membrane if it is too large?

Back

Protein doorways

Front

Does passive transport require ATP energy to move particles? (True/False)

Back

False

Front

What is a type of passive transport where materials move across a membrane without the use of ATP energy?

Back

Diffusion

Front

What type of solution has a higher concentration of water?

Back

Hypotonic solution

Front

Is equilibrium met when the concentration is even on both sides of the membrane? (True/False)

Back

True

Front

What is the process called when water moves across a membrane?

Back

Osmosis

Front

What is the term for the movement of particles from an area of high concentration to an area of low concentration?

Back

Diffusion

Front

What type of transport requires energy to move particles against their concentration gradient?

Back

Active Transport

Front

What is the main function of protein doorways in the cell membrane?

Back

To facilitate the movement of large or charged particles across the membrane.

Front

What happens to a cell in a hypertonic solution?

Back

It shrinks due to water moving out of the cell.
