Exocytosis: An Important Biological Process That Occurs in Cells Introduction (What They Are) Endocytosis and exocytosis are procedures through which elements (molecules, substances, living things) cross the cell membrane. In the case of endocytosis, the element goes from the outside into the cell. Already in exocytosis, it is transferred from the cellular interior to the exterior.
