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.

A color-blind (X-linked recessive) human with Klinefelter syndrome has parents both of whom have normal color vision. 4a. From w
sineoko [7]

The extra X chromosome is received from mother.

<h3><u>Explanation</u>:</h3>

Klinefelter's syndrome is the condition of chromosomal aberration where the person has an extra X chromosome. This means the genotype of the person is 44+XXY and the total chromosome number is 47. This condition is achieved due to inappropriate meiotic division and one of the sperm or ovum has the an extra X chromosome.

Here both the parents are normal in terms of colour vision. So the father cannot have the gene of colour blindness because if it was present, then father would have been colour blind because he has only one X chromosome per cell. So its present in mother who is heterozygous in terms of colour blind gene. So the extra X chromosome also came from her which made the presence of two defective X chromosomes in the offspring and made it colour blind.
