2. Ion channels that permit ions to pass between the interior of the cell and the extra-cellular medium are an important part of a living cell. There are multiple mechanisms that happen in an ion channel, but the simplest is that ions flow through the cell preferentially in one direction as a result of diffusion arising from a difference of ion concentrations on the inside and outside of the cell. L Cout As a first model of an ion channel, let's see how it would behave if the flux through the open channel were simply due to diffusion arising from a concentration difference. We'll model the open channel as a cylinder as shown in the figure at the left. Ас Fick's law for flow due to a concentration gradient is J = -D where D is the diffusion Ax constant and J has dimensions corresponding to number per unit area per unit time. 2.1 A typical ion channel radius is about 1 nm (nanometer), and the thickness of the cell membrane is about 7 nm. The concentration of Na+ ions inside a mammalian…

A very thin layer of oil floats on top of water. A drop of dye is placed at the center of the oil. The dye diffuses through the oil in all directions equally with a diffusion constant D0. Since the layer of oil is thin, we can assume the diffusion is two-dimensional. After a time T0 has passed, the dye has diffused a distance of 5 mm. If the dye had a diffusion constant of D0/3 what distance would the dye have diffused after a time T0/4? Give your answer in units of mm. (Round your answer to two decimal places.)
