Model a red blood cell as a spherical capacitor. The radius of a blood cell is about 6.00×10-6 m and the lipid membrane surrounding the cell is 0.100×10-6 m has a a) Calculate the capacitance of the cell b) Find the charge on the cell surface for a potential difference of 100 mV across c constant of 5.00. membrane, assuming that the interior of the cell has an equal opposite charge Find the number of hydrogen ions (H) that could cause this potential difference. c) What is the surface charge density? What is the density of hydrogen ion (H) on the surface? Does this seem reasonable? d) Proton channels can transport 105 ions per sec. Propose how the cell could establish the 100 mV potential difference in 100 milliseconds f) Patch-clamp experiments show that the maximum potential difference that the lipid membrane can have before becoming conductive is 1.00 V. What is the dielectric strength of the lipid membrane?
