Q

7 points to describe Simple Diffusion

A
  1. Movement of solutes is from High concentration to low concentration of solutes
  2. Movement continues until concentration is EQUAL
  3. Rapid over short distances
  4. Directly related to temperature
  5. Inversely related to molecular size and weight (Smaller = faster diffusion)
  6. Can happen in an open system or across a partition
  7. LIPID SOLUABLE, GASES

Q

What is Fick’s Law ?

3 points

A

Rate of Diffusion directly proportional

  • Surface area
    -membrane permeability
    -concentration gradient is larger
31
Q

7 General properties of diffusion

A
  1. Diffusion of kinetic energy
  2. Molecules diffuse from one area of high concentration of solutes to low concentration of solutes
  3. Continues until concentrations come to equilibrium
  4. Shorter distances
  5. Higher temps
  6. Smaller molecules
  7. Open system
