Cell Transport

What is the job of the cell membrane?

• Make proteins

• Fold proteins

• Direct cell's activities

• To selectively allow things in and out of the cell

The movement of water from across a cell membrane is

• Equilibrium

• Diffusion

• Osmosis

Which is true of active transport?

• It includes diffusion

• It moves molecules from High to Low concentration

• It requires energy expenditure of ATP

What will happen to a cell placed in an isotonic solution solution?

• Water will enter the cell

• Water will leave the cell

• Water will enter and leave the cell at the same rate

What will happen to a cell placed in a hypertonic solution solution?

• Water will enter the cell

• Water will leave the cell

• Water will enter and leave the cell at the same rate

Which type of transport goes from low concentration to high concentration using ATP energy?

• active transport

• passive transport

What type of solution would cause a cell to shrink and shrivel?

• isotonic

• hypertonic

• hypotonic

What type of transport is occurring in the diagram?

• diffusion

• facilitated diffusion

• active transport

What is NOT an example of passive transport?

• simple diffusion

• facilitated diffusion

• osmosis

• The sodium-potassium pump of active transport

Homeostasis is largely controlled by which organelle?

• Lysosome

• Cell Membrane

• Mitochondria

• Rough ER
