Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

Which is true about active transport?

• It requires energy
• it does not require energy
• It moves substances down the concentration gradient
• it moves material from high to low concentration

Molecules diffusing with the concentration gradient through a protein channel is...

• Facilitated Diffusion
• Simple Diffusion
• Active Transport
• Osmosis

Which of the following is moved across the plasma membrane by facilitated diffusion?

• water
• glucose
• carbon dioxide
• oxygen

This picture represents what type of cell transport?

• endocytosis
• exocytosis
• osmosis
• passive transport

Exocytosis is a 

• type of passive transport 
• mechanism by which cells ingest other cells 
• transport process in which vesicles are formed from pouches in the cell membrane 
• way for cells to release large molecules, such as proteins 

Movement across the cell membrane that does not require energy is called

• active transport
• passive transport

Which of the following is not an example of active transport?

• Sodium potassium pump
• endocytosis
• exocytosis
• facilitated diffusion

If a molecule passes through a protein, but goes down a gradient, it is called

• active transport
• endocytosis
• facilitated diffusion
• exocytosis
