Cellular Process

Movement of water from an area of higher concentration to an area of lower concentration. 

• Facilitated Diffusion

• Active Transport

• Osmosis

• Diffusion 

In osmosis, water moves ________ areas of higher solute concentration.

• into

• up

• down

• out of

Equilibrium refers to when the concentration of molecules on one side of the membrane are _________ to the other side of the membrane.

• Greater than or equal to

• Less

• Equal

• Greater

What is the main difference between diffusion and facilitated diffusion?

• Diffusion requires the help of a protein to transport molecules, whereas in facilitated diffusion the molecules transport directly across the membrane.

• Diffusion requires energy, whereas facilitated diffusion does not require energy.

• Facilitated diffusion requires the help of a protein to transport molecules, whereas in diffusion the molecules transport directly across the membrane.

• Facilitated diffusion requires energy, whereas diffusion does not require energy.
