The three fundamental classes of proteins involved in transport across membranes are:
i) channelsii) pumpsiii) exchangers
For each class, describe its essential features, explain how transport is accomplished and name at least one representative example.
Explain the difference between simple and facilitated diffusion. This is a hw question
Why is simple diffusion the only possible mechanism of potential movement of molecules across the dialysis membrane in experiment 2?
