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

• diffusion
• osmosis
• facilitated diffusion
• active transport

Osmosis is the diffusion of __________.

• water
• glucose

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.
