Calculating conductivity of the cell interior and the blood

Click For Summary
SUMMARY

The discussion focuses on calculating the conductivity of the cell interior and blood based on ion concentrations. The provided ion concentration table includes Potassium (K+), Sodium (Na+), and Chloride (Cl-) with specific values for both the cell and blood. To compute conductivity, one must utilize the formula that incorporates ion concentration and mobility. The key ions and their concentrations are essential for accurate calculations, which are critical for understanding physiological processes.

PREREQUISITES
  • Understanding of ionic conductivity principles
  • Familiarity with ion concentration measurements
  • Knowledge of the Nernst equation
  • Basic proficiency in mathematical calculations involving concentrations
NEXT STEPS
  • Research the Nernst equation for calculating equilibrium potentials
  • Learn about ionic mobility and its impact on conductivity

They give me a table of ion concentrations of the most common ions in the cell interior and in the blood. I am asked to calculate the conductivity of the cell interior and that of the blood. I have no idea how to calculate conductivity if I only know the concentrations. Here is the table I am provided with

Ion, Ion concentration in cell, Blood
K+, 140, 4
Na+, 10, 145
CL- , 5, 116


Any help would be appreciated ASAP. This assignment is due tomorrow so I would really appreciate any advice!
