Diffusion and Osmosis Quiz

_____________ is the free movement of particles across the membrane with the concentration gradient

• diffusion

• facilitated diffusion

• active transport

• fusion

An example of diffusion is

• CO₂ and O₂ exchange in the lungs

• Glucose transport

• Na⁺ / K⁺ Pumps

• Exocytosis

The condition in which all acting influences are balanced.

• equilibrium

• dynamic equilibrium

• net movement

occurs when the concentration of particles is higher in one area than another.

• concentration gradient

• concentration

• [high] --> [low]

Where is the water at a higher concentration?

• outside the cell

• inside the cell

More water outside of the cell.

Hint: high ---> _____

• move into cell

• move out of cell
