The process of moving materials from the cell into the extracellular fluid.
The materials from the cells are released in form of vesicles.
This process helps in the removal of cellular waste from the cell outside.
Types of exocytosis:
Constitutive exocytosis: Exocytosis which requires no signal is required for releasing the secretory materials outside the cell and is called constitutive exocytosis.
Regulated exocytosis: The exocytosis which requires an external signal for releasing secretory materials outside the cell is called regulated exocytosis.
