WebNational Center for Biotechnology Information WebIn cells, some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly, while others must pass through membrane proteins in a process called facilitated diffusion. Here, we’ll look in more detail at membrane permeability and different modes of passive transport.

5.6: Bulk Transport by Endocytosis and Exocytosis

WebEndocytosis is a type of active transport that moves particles, such as large molecules, parts of cells, and even whole cells, into a cell. There are different variations of endocytosis, but all share a common characteristic: The plasma membrane of the cell invaginates, forming a pocket around the target particle. http://chemsite.lsrhs.net/ChemicalBonds/LargeMolecules.html bismarck shipwreck coordinates
