Cell Transport

What is the purpose of the cell membrane?

• Make proteins for the cell

• Controls what comes in and out of the cell

• Produces energy for the cell

• Transports stuff around the cell

What kind of energy is used in active transport?

• ENERGY IS NOT USED IN ACTIVE TRANSPORT!!!!!

• Solar Energy

• ATP

• Mechanical Energy

In passive transport, in what direction do particles move?

• High to low concentration

• Out of the cell

• Low to high concentration

• Into the cell

In active transport, in what direction do particles move?

• High to low concentration

• Out of the cell

• Low to high concentration

• Into the cell

Which statement is correct? (choose 2)

• In passive transport; particles move against the concentration gradient

• In passive transport; particles move up the concentration gradient

• In passive transport; particles move with the concentration gradient

• In passive transport; particles move down the concentration gradient

Which statement is correct? (choose 2)

• In active transport; particles move against the concentration gradient

• In active transport; particles move down the concentration gradient

• In active transport; particles move with the concentration gradient

• In active transport; particles move up the concentration gradient

In a hypotonic solution. (Hint: Draw a picture)

• Water goes out of the cell because there is less water outside than inside the cell.

• Water goes out of the cell because there is more water outside than inside the cell.

• Water goes into the cell because there is less water outside than inside the cell.

• Water goes into the cell because there is more water outside than inside the cell.

The cell membrane maintains...

• Energy

• The cell looking good

• Phospholipid bilayer

• Homeostasis/Equilibrium

In a hypertonic solution, the cell...

• Gets smaller

• Gets bigger

• Stays the same

• Bursts

If there is more water outside the cell than inside the cell, the solution is...

• hypertonic

• isotonic

• hypotonic

• heteromitomonotonic
