if you were to watch an individual neurotransmitter molecule just after it was released what would happen to it
Olenka [21]

Neurotransmitter leaves the presynaptic cell by exocytosis. It is released in the synaptic space, and moves to the postsynaptic membrane to meet its receptor. When binding occurs, it triggers a response in the new cell.

-----------------------------------------

Every neuron forms connections with another cell.  

When a presynaptic cell sends information, a neurotransmitter is released.  

After the exocytosis event, this chemical substance travels through the synaptic space forward to the other cell. Once there, it binds to its receptors in the postsynaptic membrane.  

When the joining occurs, the receptor acquires a channel shape. This change allows the ion transference that will make possible the modification of the action potential.  

This binding produces the excitatory postsynaptic potential -depolarization-.

A new action potential initiates in the postsynaptic cell and spreads to the rest of the membrane, depolarizing it.

If the communication between cells needs to stop, the neurotransmitter will be taken out from the synaptic space <em>instead of binding to its receptor. </em>

There are two mechanisms by which the neurotransmitter can be eliminated: by deactivation or reuptake.

How many new volumes would each new cell contain whenever a cell splits?
Elenna [48]
The specific volume will be different for various kinds of cells. The safe answer would be that the new cell will pretty much have the same volume as the one that it divided from. This is true for most eukaryotic cells unless other factors like epigenetics or mutations come into place.

One example of moments a cell would increase in volume is during hypertrophy. This simply means that the cell is increasing in size (compared to: hyperplasia -- which is an increase in number of the cells). Hypertrophy is definitely an increase in volume of the cell but this doesn't necessarily translate to cell division (i.e. just because the cell is big now, doesn't mean it will still be big when it divides).

Another moment of increasing volume of the cell and now also related to cell division would be during the two stages in the cell cycle (i.e., G1 and G2 phases). This is the growth phase of the cell preparing to divide. However when mitosis or division happens, the cells will normally end with the same volume as when it started.

This are safe generalizations referring to the human cells. It would help if a more specific kind of cell was given.
