suppopse you were going to deisgn a system for the rapid diffusion of oxygen across a phosphlipid bilayer. according to fick's law, which aspects of the system should be maximized and which should be minimized in order to maximize the diffusion rate?

According to Fick's law, the rate of diffusion of any substance across any barrier is directly proportional to the surface area of the membrane or any layer exposed. and the concentration of the diffusing substance available, but the rate is inversely proportional to the diffusion distance available.

Thus the rate at which oxygen will move across the phospholipid bilayer will depend on the concentration or amount per mole of the oxygen molecule hitting the phopholipid at a prticular time and how permeable the phospholipd layer is to oxygen molecules, but the rate of its movement across will be reduced as the distance between the phosphoslipid bilayer and the diffusing molecules increases.

Therefore, the concentration of oxygen should be maximised, the surface area of the phospholipid bilayer should also be maximized. the distances between the phopholipid and the vessel containing the diffusing oxygen molecules should be drastically reduced. With this Fick's law has been applied, and therefore maximum oxygen molecules can diffuse across.
