What is facilitated diffusion?

• Transport that uses proteins to help move molecules across the membrane. 
• Movements of substances through a membrane. 
• When molecules spread from High to Low concentration on their own. 
• When pressure pushes something through a membrane. 

Which of the following is the best example of osmosis? 

• NA/K Pump 
• Water moving though the cell membrane 
• Kidneys 
• Photosynthesis 

Active transport does not require energy.

• True 
• False 

Molecules using simple diffusion move from 

• high to low concentrations 
• low to high concentrations 
• no concentrations  
• both concentrations  

Solutes move with the concentration gradient, therefore no energy is used. 

• Passive Transport
• Active Transport

Solutes move against the concentration gradient, therefore energy is needed. 

• Passive Transport
• Active Transport
