    The small molecule cyclic ATP takes about 0.2 second to diffuse 10 μm, on average, in a cell. Suppose that ATP is produced near the plasma membrane on one end of the cell; how long will it take for this cAMP to diffuse through the cytosol and reach the opposite end of a very large cell, on average? Assume that the cell is 200 μm in diameter.

    would anyone know how to calculate this? I'm assuming its 4 seconds..
