When we think of membrane transport, we often think first of ATP-dependent, active mechanisms. However, it is also true that passive diffusion of ions and molecules plays an important role in many physiological systems. For each of the following situations, indicate whether ACTIVE or PASSIVE membrane transport is used, or if BOTH forms of transport may be used.

Select the equations used when solving the above problem:  (The original problem: A box of 10.0 cm x 10.0 cm x 10.0 cm contains 1.2 x 105 Pa of N2 gas molecules at 25°C.  The mass of one N2 molecule is 4.68 x 10-26 kg and its molar mass is 28.0-g.  Assume all the molecules collide with the container walls with its rms speed in a head-on fashion and all the collisions are perfectly elastic, estimate the amount of molecules striking one side of the container wall in 10 seconds? )
