e. All could limit protein mobility
Explanation:
Plasma membrane proteins perform a variety of functions: they act preferentially on transport mechanisms, organizing true tunnels that allow substances to pass into and out of the cell, function as membrane receptors, among other functions. These proteins vary greatly in their mobility, some are as mobile as lipids, while others are practically immobile. But FRAP has revealed that some proteins move in cell membranes much more slowly than in reconstituted liposomes. This limited mobility can be explained by the statement in alternative "E" of the above question.
