Endocytosis Definition. Endocytosis is the process of actively transporting molecules into the cell by engulfing it with its membrane. Endocytosis and exocytosis are used by all cells to transport molecules that cannot pass through the membrane passively. Exocytosis provides the opposite function and pushes molecules out of the cell. Exocytosis is an important process in neurons, the cells of the nervous system. Neurons are electrochemical cells that facilitate communication in animals. Neurons send an electrical signal down a ... Exocytosis is the process of moving materials from within a cell to the exterior of the cell. This process requires energy and is therefore a type of active transport. Exocytosis is an important process of plant and animal cells as it performs the opposite function of endocytosis.In endocytosis, substances that are external to a cell are brought into the cell.
