This picture show the molecules getting help across the membrane.  The vocabulary word that best describes this is

• diffusion

• osmosis

• facilitated diffusion

• active transport

How is diffusion (left) different from the process on the right?

•  Diffusion takes place due to osmotic pressure. 

• Diffusion requires cellular energy for the transfer of molecules.

• Diffusion requires protein channels as a passage-way for particles

• Diffusion transfers particles from an area of high to low concentration. 

Describe the movement of molecules going through the proteins in the illustration.

• Molecules are moving from a higher concentration to a lower concentration.

• Molecules are moving from a lower concentration to a higher concentration.

• Molecules are moving from a higher concentration to a lower concentration and then from a lower to higher concentration.

• Molecules are moving from a lower concentration to a higher concentration and then from a higher concentration to a lower concentration.
