German scientist Adolf Fick discovered that the rate of diffusion is directly proportional to the concentration gradient (∆cs /∆x)—that is, to the difference in concentration of substance s (∆cs ) between two points separated by the distance ∆x. According to Fick’s first law,

#Unit 6. System Physiology – Plant
  1. The movement of molecules by diffusion always proceeds nonspontaneous, down a gradient of concentration or chemical potential, until equilibrium is reached, movement of molecules is termed passive transport
  2. The rate of accumulation (or depletion) of concentration within the volume as proportional to the local curvature of the concentration gradient
  3. A substance will diffuse faster when the concentration gradient becomes steeper (∆cs is large) or when the diffusion coefficient is increased
  4. A cell membrane potential to standard potential and to the activities of the electroactive, relates the effective concentration
