Experiment 5: Exploring facilitated transport

Experiment 5 consists of two experiments – Experiments 5.1 and 5.2. In Experiment 5.1 the objective is to examine how membrane transporters can facilitate the speed of penetration of solutes into a cell and In Experiment 5.2 the objective is to examine how such facilitated diffusion interacts with solute size.

Again, as in Experiment 4, we will replace the water in the external solution with some other molecule that will penetrate but either through a facilitated diffusion process, which allows it to go across the membrane faster than having to dissolve in and cross through the lipid bilayer, or by passive diffusion in which the molecule has to dissolve in and cross through the lipid bilayer
