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 does removing trees affect nitrogen cycling in a forest ecosystem? A. After clearcutting, more soil nitrogen was exported vi
mina [271]

Answer:

B. After clearcutting, plant uptake stopped and nitrogen accumulated in the soil.

Explanation: Clear cutting leaves the soil bare and allows for direct penetration of sunlight this increases the soil temperature which favors the activity of soil microrganism. This microrganism activity increase the production of ammonium and nitrate hence the increase in soil Nitrogen level. Clearcutting then allows for accumulation of Nitrogen produce due to removal of plant or forest tree that could use up the Nitrogen produced.
