LT 4.2 and 4.3 Review

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.

Which component of the cell membrane functions to help move larger materials across the membrane?

• carbohydrates
• cholesterol
• phospholipids
• proteins

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.

What type of transport is this?

• facilitated diffusion
• active transport
• diffusion
• osmosis

When cells form a vesicle to take in materials, which form of transport is occurring? 

• Endocytosis
• Exocytosis
• Facilitated Diffusion
• Osmosis

Active transport across a cell membrane from low to high concentration, requires

• energy (ATP)

• no energy

• water

• oxygen

These type of molecules move by diffusion.

• small, nonpolar, uncharged

• small, polar

• large, charged, polar

• small, nonpolar, charged

Osmosis is the passive transport of what?

• oxygen molecules
• water molecules
• glucose molecules
• carbon dioxide molecules

These type of molecules would use facilitated diffusion.
