No energy is used [High]  [Low] (it’s the natural flow) This means it goes down a concentration gradient.

Facilitated Diffusion

Compare and contrast diffusion and facilitated diffusion.

Facilitated Diffusion = diffusion through transport proteins charged atoms (ions) and size- larger molecules goes through transport (channel) proteins http://bcs.whfreeman.com/thelifewire/content/chp05/0502001.html

Example Glucose enters cells Use hand out to go along with this: 1. ___Insulin__ binds to a___ receptor_____ protein. 2. This causes a ____signal___ to be sent telling ___vesicles_____ containing glucose______transport___ proteins to move to and fuse with the ___cell membrane_______. 3. Glucose moves from __high___ concentration to ___low____ concentration as it enters body cells through the __receptor___ proteins by the process of ___facilitated diffusion______________. animation of this process: http://reddymed.com/diabetes/treatment_insulin.html connected to diabetes: YouTube Video
