The process by which materials are released from a cell is called exocytosis.
What is exocytosis?
Exocytosis is the process where substances inside a cell are packaged into vesicles and then released to the outside when those vesicles fuse with the cell membrane. It is essentially the cell’s way of exporting materials like hormones, enzymes, neurotransmitters, or waste products into the extracellular space.
How it works (simple steps)
- Materials (such as proteins or waste) are enclosed in a membrane-bound vesicle inside the cell.
- The vesicle moves toward and docks at the plasma membrane.
- The vesicle membrane fuses with the plasma membrane.
- The contents of the vesicle are released outside the cell.
A classic example is a neuron releasing neurotransmitters at a synapse through exocytosis.
Quick exam-style fill‑in

→ Answer: exocytosis.
TL;DR: Materials are released from a cell in a process called exocytosis , where vesicles fuse with the cell membrane and dump their contents outside.
