Web animations of membrane transport mechanisms

Emphasizing protein structure and binding
Lactose transport animation showing detailed protein structure (actually a case of co-transport with proton)

Specific transport mechanisms- animations

review of cell transport mechanisms (Wisconsin)
the last 2 - receptor-mediated endocytosis; exocytosis - are the most useful
