Question

which term names the process whereby molecules in vesicles are exported out of the cell?
○ osmosis
○ exocytosis
○ diffusion
○ endocytosis

Explanation:

• Osmosis is the movement of water across a semipermeable membrane.
• Exocytosis is the process where vesicles fuse with the cell membrane to release molecules out of the cell.
• Diffusion is the movement of molecules from high to low concentration.
• Endocytosis is the process of bringing molecules into the cell via vesicles.

So the correct term for exporting molecules in vesicles out of the cell is exocytosis.

Answer:

B. exocytosis (assuming the options are labeled with letters, if not, the correct option is the one with "exocytosis")
