How are large molecules taken into a cell
WebThere are two types of bulk transport: Endocytosis and Exocytosis. Endocytosis. The process of TAKING IN liquids or fairly large molecules into a cell by engulfing them in a membrane (endo- in) Exocytosis. Release of substances out of a cell by the fusion of a vesicle with the membrane. Opposite of Endocytosis.
