WebbSort the following types of membrane transport mechanisms into active or passive processes. Active Process: Secondary active transport, Primary active transport, Endocytosis, Exocytosis. Passive Process: Simple diffusion, Facilitated diffusion, Osmosis. The cellular plasma membrane is selectively permeable, which means some materials … WebbFacilitated diffusion is the passive movement of molecules across the cell membrane via the aid of a membrane protein. It is utilised by molecules that are unable to freely cross the phospholipid bilayer (e.g. large, polar molecules and ions) This process is mediated by two distinct types of transport proteins – channel proteins and carrier ...
