Exocytosis

 

Exocytosis – Simple Definition:

Exocytosis helps the cell push things like waste or proteins out of the cell using vesicles.

Exocytosis is a process where a cell pushes materials (like waste or proteins) out of the cell using a vesicle.

🧠 How it works (in simple steps):

1. The cell packs the material inside a vesicle (a small bubble made of membrane).

2. The vesicle moves to the cell membrane.

3. The vesicle joins with the membrane.

4. The contents are released outside the cell.

🧪 Examples:

• Nerve cells use exocytosis to release neurotransmitters.

• Pancreas cells release insulin by exocytosis.

• Cells remove waste this way too.
