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
