Passive Transport is powered by the movement of molecules from a low concentration to a high concentration.

• True
• False

There are 3 Biomolecules that make up the plasma membrane 1. Lipids, 2. Proteins and 3. _________

• Lipids
• Carbohydrates
• Proteins

Simple Diffusion is a type of Active Transport

Unlike Facilitated Diffusion, Simple Diffusion is able to use the concentration gradient to move SMALL NON-POLAR molecules across the plasma membrane.

• True
• False

Passive Diffusion can be described as molecules moving DOWN the concentration gradient, from high to low, because it is powered by ATP.

• True
• False

Which type of diffusion is being represented in this picture?

• Passive Diffusion
• Simple Diffusion
• Active Diffusion
• Facilitated Diffusion

Why do the molecules stop moving across the membrane?

• There is still a homeostatic imbalance.
• The molecules grew into a larger size
• The concentration gradient is now gone
• The molecules are still moving
