EndocytosisEndocytosis is a process whereby cells absorb material (molecules such
as proteins) from the outside by engulfing it with their cell
membrane. It is used by all cells of the body because most substances
important to them are large polar molecules, and thus cannot pass
through the hydrophobic plasma membrane. The function of endocytosis
is the opposite of exocytosis.
