Large molecules in/out of cells

{ from http://bcs.whfreeman.com/thelifewire8e/pages/bcs-main_body.asp?s=05000&n=00010&i=05010.01&v=&o=&ns=0&uid=0&rau=0 }

Endocytosis is the transport of macromolecules – large particles – and small cells into eukaryotic cells

Occurs through engulfment, and vesicle formation, from the cell membrane.

Phagocytosis and pinocytosis are types of endocytosis.

In receptor-mediated endocytosis, a specific receptor protein on the plasma membrane binds to a particular macromolecule.

In exocytosis, materials in vesicles are secreted from the cell when the vesicles fuse with the plasma membrane.
