IP BIO Cell Membranes The membrane of a living cell can be
approximated by a parallel-plate capacitor with plates of area 4 7510 9 . Ã ,
- m2 a plate
separation of 8 5 10 9 . Ã
- m, and a dielectric with a dielectric constant of 4.5. (a) Whatis
the energy stored in such a cell membrane if the potentialdifference across it is
0.0725 V? (b) Would your answer to part (a) increase, decrease, orstay the same if
the thickness of the cell membrane is increased? Explain.
