Final answer:
Exocytosis is the process by which internal materials are transported towards the extracellular space of the cell.
Step-by-step explanation:
Exocytosis is the term that describes the process of internal materials being transported towards the extracellular space of the cell. It is the opposite of endocytosis, as it involves expelling waste material from the cell into the extracellular fluid. In exocytosis, waste material is enveloped in a membrane and fuses with the interior of the plasma membrane, allowing the waste material to be expelled into the extracellular space.
