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.

4. What does a total solar eclipse look like from Earth?

EastWind [94]

4. When you look up to the sky, it appears as a dark circle with halo light at its edges moving across the face of the sun. As it does, depending on the relative position of the person on earth – that determines where they are on the umbra or penumbra of the eclipse, the place becomes a daytime twilight (umbra) or partial twilight (penumbra).

5. A new moon is formed when the moon is in between the sun and the earth. This is converse to the case of a lunar eclipse where the earth is between the sun and moon. In a new moon, the face of the moon that is faced towards the earth is dark because it is not lit by the sun. It is important to note that a solar eclipse is not formed because the moon’s orbit, around the earth, is tilted at an angle.

Scorpion4ik [409]

Answer:

Cells are the basic unit of matter is the correct answer.

Explanation:

The other answers are all a part of the cell theory, but that one is NOT and since the question is asking for the incorrect one, that's the answer. :)
