Evol 1 Old Topic Cell Transport

Which of the following is not a correct statement to describe the term dynamic equilibrium?

• The water continues to flow into the cell, but at a slower rate

• The water moves back and forth at the same rate

• The cell maintains a stable shape

• The cell is in an isotonic solution

Passive transport requires

• no energy because it moves from an area where it is less concentrated to more concentrated

• energy because it moves from an area where it is less concentrated to more concentrated

• no energy because it moves from an area where it is more concentrated to less concentrated

• energy because it moves from an area where it is more concentrated to less concentrated

Base on this image, the sodium potassium pump

• require energy to move both sodium out and potassium in due to the fact they move against the gradient

• require energy to move sodium out since it is going from high to low concentration.

• require energy to move potassium in since it is going from high to low concentration.

• does not require energy for the movement of either potassium or sodium since the both go from high to low concentation

What is the movement of particles with the concentration gradient using carrier or channel proteins?

• diffusion

• facilitated diffusion

• active transport

• enzymatic reactions

If a plant cell containing 5% salt is placed into a glass of water with 20% salt. What will happen to the cell?

• It will shrink as water moves out of the cell by active transport

• It will shrink as the water moves out by osmosis

• It will swell as water moves in by osmosis

• It will swell as water moves in by active transport.

Movement of water is always towards the ______________ solution which contains _________ solute (meaning less water).

• hypotonic, less

• hypotonic, more

• hypertonic, less

• hypertonic, more
