Diffusion:

• Equilibrium - when there is an even distribution of solute molecules in the solvent

  • Solute - The molecule being dissolved

  • Solvent - The liquid or gas doing the dissolving

There are 2 main types of diffusion:

• Simple

  • Molecules moving from an area of high concentration

    • Random motion drives diffusion

    • Movement is based on kinetic energy(speed), charge, and mass of molecules

• Facilitated

Concentration Gradient:

• Concentration is the measurement of how many particles are dissolved in the liquid

  • High concentration = more particles

  • Low concentration = fewer particles

Passive Transport:

• Diffusion across the membrane

  • Movement of particles from high → low concentrations

    • They must be relative to each other
