Question

A class of chemicals called neurotransmitters is important in the transmission of nerve impulses. Neurotransmitters are packaged by the cell into small, membrane-bound sacs called vesicles. Upon receiving a chemical signal, the vesicles move towards the cell membrane and fuse with it, releasing the enclosed neurotransmitters from the terminal end of the nerve cell. Which organelle is most likely responsible for packaging neurotransmitters into a vesicle?

Answer 1

The organelle Golgi apparatus or Golgi complex is another packaging organelle within the cell, one of which is the endoplasmic reticulum. It's main function is to gather simple molecules to form larger macromolecules then pack them into vesicles.
