Question
Correctly order the steps for the process of exocytosis.
Solution
-
The cell creates a vesicle around the material that needs to be expelled. This is often waste material or a product of the cell's function that needs to be transported elsewhere.
-
The vesicle, containing the material, moves through the cytoplasm of the cell towards the cell membrane.
-
The vesicle then fuses with the cell membrane. This is facilitated by the interaction of specific proteins on both the vesicle and the cell membrane.
-
The contents of the vesicle are then expelled out of the cell as the vesicle membrane becomes part of the cell membrane.
-
The material is now outside of the cell and can be transported to where it needs to go. This process is known as exocytosis.
