A simplified model for an erythrocyte is a spherical capacitor with a positively charged liquid interior of surface area A. The interior fluid is separated by a membrane of thickness b from the surrounding, negatively charged, plasma fluid. The potential difference across the membrane is 128 mV, and the thickness of the membrane is about 100 nm with a dielectric constant of κ = 5.1. Use 1.06 g/cm3 as the density of blood.

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space.

Let’s consider a spherical cell (it’s a simplified model) with conducting fluids inside and out and an insulating membrane in between. The capacitance of the cell membrane is 90 pF; the resistance across the membrane is 30 MΩ. Under normal circumstances, the potential inside the cell is 70 mV than the potential outside. An action potential is triggered if the motion of charges across the cell membrane changes this potential difference by 15 mV. 1) If the thickness of the...

The net charge difference across the membrane, just like the charge difference across the plates of a capacitor, is what leads to the voltage across the membrane. How much excess charge (in picocoulombs, where 1 pc = 1x10-12 C) must lie on either side of the membrane of an axon of length 2 cm to provide this potential difference (0.07 V) across the membrane? You may consider that a net positive charge with this value lies just outside the axon...

A typical cell has a membrane potential of -70 mV, meaning that the potential inside the cell is 70 mV less than the potential outside due to a layer of negative charge on the inner surface of the cell wall and a layer of positive charge on the outer surface. This effectively makes the cell wall a charged capacitor. Because a cell's diameter is much larger than the wall thickness, it is reasonable to ignore the curvature of the cell...

Cell Membranes and Dielectrics Many cells in the body have a cell membrane whose inner and outer surfaces carry opposite charges, just like the plates of a parallel-plate capacitor. Suppose a typical cell membrane has a thickness of 8.4×10−9 m , and its inner and outer surfaces carry charge densities of -5.3×10−4 C/m2 and +5.3×10−4 C/m2 , respectively. In addition, assume that the material in the cell membrane has a dielectric constant of 5.4. Part A Find the direction of...
