This video shows acetylcholine molecules inside a synaptic vesicle. The actual concentration of the neurotransmitter is about five times higher in a vesicle ready for release, and the empty-looking space is mostly water and other substances. | Ribosome Studio

It's important to note that the concentration of acetylcholine in a vesicle primed for exocytosis is approximately 5x higher than what's shown here. Furthermore, the seemingly empty space between the molecules is not truly empty. It's actually filled with other substances, primarily water. | Ribosome Studio | Facebook
