Question
Nerve cells maintain a charge
separation across their cell membrane.
The cell membrane of a particular cell is
29.14
10 nm thick and the cell can be modeled
as a cylinder with a diameter of 12 um
and a length of 80 µm. If the potential
difference across the cell membrane is
90 mV, what is the charge stored on the
cell? (you can assume that ɛ, = 1 and
you should use the total surface area of
the cell in the calculation)
29.15 How much energy is stored in the
form of charge separation in the cell in
Problem 29.14?
