Located on the cell membrane surface, nucleus membrane or other cellular organelle membrane - they can bind to corresponding proteins to initiate cellular signaling pathways (reactions).

• carrier protein

• channel protein

• receptor protein

_____________ is the free movement of particles across the membrane with the concentration gradient

• diffusion

• facilitated diffusion

• active transport

• fusion

What is a difference between diffusion and facilitated diffusion?

• movement of particles from [high] to [low]

• a protein "helper"

• movement of particles from [low] to [high]

• energy

Endocytosis is defined as

• the movement of large molecules from the inside of the cell to the outisde of the cell using channel proteins. 
• the movement of large molecules from the inside of the cell to the outisde of the cell membrane vesciles. 
•  the movement of large molecules from the outside of the cell to the inside of the cell using membrane vesciles.
• the movement of large molecules from the outside of the cell to the inside of the cell using channel proteins. 

Active transport _______ and is the movement of a substance from _____ to _____ concentration

• requires energy, high to low
• requires no energy, low to high
•  requires no energy, high to low
•  requires energy, low to high
