3) Electrical model of a cell membrane Consider a piece of cell membrane. The membrane has a specific conductivity of Om = 10-10 (12 cm)', a dielectric constant Em = 8 and thickness dm = 7.5 nm. On both sides of the membrane are two boundary layers with equal specific conductivity Op = OL = 102 (2 cm)-1. The thickness of these layers is dp = 50 nm and di = 100 nm and their capacitance is negligible. a) What...

The thickness of the cell membrane is 0.10 in a typical Iiving cell, the electric potential inside the cell s 70 miv lower than the electric potential outside the cell microns.What is the magnitude of the electric field within the cell membrane? 0.00000143 X NIC (or V/m)
A typical cell membrane is 8.15 nm thick and has an electrical resistivity of 1.35E+7 Ω·m. If the potential difference between the inner and outer surfaces of a cell membrane is 78.2 mV, how much current flows through a square area of membrane 1.07 μm on a side? Suppose the thickness of the membrane is quadrupled, but the resistivity and potential difference remain the same. How much current flows through the same area of membrane now?
A typical cell membrane is 7.96 nm thick and has an electrical resistivity of 1.40E+7 Ω·m. If the potential difference between the inner and outer surfaces of a cell membrane is 71.7 mV, how much current flows through a square area of membrane 1.12 μm on a side? b) Suppose the thickness of the membrane is doubled, but the resistivity and potential difference remain the same. How much current flows through the same area of membrane now?
A cell membrane has a surface area of 1.2 × 10−7 m2, a dielectric constant of 5.5, and a thickness of 7.1 nm. The potential difference across the membrane is 60 mV.
