Cell transport 2

Which is NOT a function of the cell membrane

• Determines what exits the cell

• It dissolves in water

• Determine what enters the cell

• Contains proteins to help pass molecules

Passive energy require....

• energy

• no energy

In passive transport, molecules move from

• H to L

• L to H

Check all that are types of passive transport

• Osmosis

• Diffusion

• Facilitated Diffusion

• Endocytosis

What is moved in osmosis

• O2

• H2O

• Na+

• Glucose

A cell that is made of 60% salt is placed in a solution containing 30% salt. Where will the water move?

• Into the cell

• Out of the cell

Define passive transport

• Movement of water across the cell membrane through an aquaporin

• Movement of materials across the cell membrane that uses ATP

• Movement of materials across the cell membrane that does not use ATP

• Movement of materials across the cell membrane that uses energy

A type of passive transport in which transport proteins HELP molecules enter and exit the cell is called...

• Simple diffusion

• Concentration gradient

• Facilitated diffusion

• All of the above

A type of facilitated diffusion in which water moves from high to low concentration across the cell membrane

• Carrier protein diffusion

• Simple diffusion

• Ion channel diffusion

• Osmosis
