- High Concentration - Low Concentration
- Concentration Gradient
- Relatively equal concentration
- Dynamic Equilibrium
- "Dynamic" because the
particles are always moving
- Partially Permeable Membranes
Anlagen:
- Only allows certain sized
molecules to pass
through
- Membrane with many tiny gaps
for molecules to pass through
- Biology - Examples of
Diffusion in nature
- Cell Membrane
- Diffusion of
Glucose into
cells
- Neurons
- Diffusion of
Neurotransmitters
- Digestion
- Diffusion of
Glucose int
Bloodstream
