Cell Transport and Cell Membrane

Describes the arrangement of the cell membrane as bendable and made of many parts.

How does a cell maintain homeostasis?

• Regulates what enters and leaves the cell
• Flexibility
• Protective barrier
• Structure and support

The cell membrane is selectively permeable, which means...

• All materials can enter and leave the cell
• Certain things can enter while others cannot
• The cell manually sorts through all materials
• Only certain cells can interact with the cell.

The picture is an example of...

• active transport
• passive transport
• diffusion
• osmosis

Osmosis uses a channel protein called AQUAPORIN.  What type of transport is this? *Think!

• Diffusion
• Facilitated Diffusion
• Active Transport
• Endocytosis

What is one major difference between passive and active transport?

• Passive transport uses energy; active transport does not.
• Both types of transport use energy.
• Active transport uses energy; passive transport does not.
• No difference. They are both the same.

Small, non-polar molecules like CO₂ and O₂ and NO can pass through the cell membrane using what type of transport?

• Diffusion
• Osmosis
• Facilitated Diffusion
• Endocytosis

Movement of molecules from an area of high concentration to an area of low concentration is

• diffusion 
• passive transport
• osmosis
• all of the above

If a red blood cell is put in distilled water, what will most likely happen to the cell?

• Nothing will happen

• It will shrivel.

• It will burst and then shrivel up

• It will swell and burst

What is equilibrium?

• When concentrations cannot be balanced between two substances 
• When concentrations are balanced between two substances 
• Making the energy in the top half of your body equal the the energy in the bottom half
• Concentrations do not exist
