• Do you know what to use the Nernest equation for? What factors does it take into account?


  Used to calculate the equilibrium potential (in mV) for an ion

  Takes into account; temperature, charge of ion, and the external and internal ion concentrations
• Do you understadn the concepts and general principles of equilibrium potential?

  1. Each ion has their own equilibrium potential
  2. Each ion is affected by the electrical and chemcial gradient
  3. Chemical gradient is independent of the concentration of other ions
  4. Electrical gradietn depends on all the charges within the cell and exert an equivalent effect on all ions
