The voltage across the membrane forming a (Biological) cell wall is about 74 mV and the membrane is about 8.7 nm thick. 4c. Molecular changes are sometimes measured with the energy unit of "electron-volt" (eV), where 1eV=1.602×10−19J. For context, a single photon of visible light has an energy of about 2eV. How many eV does it cost to move a doubly-ionized Ca++ ion the hard way across the cell membrane?

Consider electrons flowing in copper. a) Compute the average time between collisions for free electrons in copper. (Hint: The density of free electrons in copper is 8.44 x 1028 electrons / m3). b) Due to quantum mechanical effects, electrons in copper have a speed of about 106 m/s at room temperature. Show that electrons moving at such speeds will travel an average distance of 25 nanometers between collisions.
